They walk too far away to hear any more. + +Late at night, you sneak to the warehouse - who knows what kinds of paradoxes you could cause if you were discovered - and use your fancy wrist device to quickly scan every box and produce a list of the likely candidates (your puzzle input). + +To make sure you didn't miss any, you scan the likely candidate boxes again, counting the number that have an ID containing exactly two of any letter and then separately counting those with exactly three of any letter. You can multiply those two counts together to get a rudimentary checksum and compare it to what your device predicts. + +For example, if you see the following box IDs: + + abcdef contains no letters that appear exactly two or three times. + bababc contains two a and three b, so it counts for both. + abbcde contains two b, but no letter appears exactly three times. + abcccd contains three c, but no letter appears exactly two times. + aabcdd contains two a and two d, but it only counts once. + abcdee contains two e. + ababab contains three a and three b, but it only counts once. + +Of these box IDs, four of them contain a letter which appears exactly twice, and three of them contain a letter which appears exactly three times. Multiplying these together produces a checksum of 4 * 3 = 12. + +What is the checksum for your list of box IDs? + +--- Part Two --- + +Confident that your list of box IDs is complete, you're ready to find the boxes full of prototype fabric. + +The boxes will have IDs which differ by exactly one character at the same position in both strings. For example, given the following box IDs: + +abcde +fghij +klmno +pqrst +fguij +axcye +wvxyz + +The IDs abcde and axcye are close, but they differ by two characters (the second and fourth). However, the IDs fghij and fguij differ by exactly one character, the third (h and u). Those must be the correct boxes. + +What letters are common between the two correct box IDs? (In the example above, this is found by removing the differing character from either ID, producing fgij.) diff --git a/www/statics/aoc/2018/02_input.txt b/www/statics/aoc/2018/02_input.txt new file

+You've managed to sneak in to the prototype suit manufacturing lab. The Elves are making decent progress, but are still struggling with the suit's size reduction capabilities. + +While the very latest in 1518 alchemical technology might have solved their problem eventually, you can do better. You scan the chemical composition of the suit's material and discover that it is formed by extremely long polymers (one of which is available as your puzzle input). + +The polymer is formed by smaller units which, when triggered, react with each other such that two adjacent units of the same type and opposite polarity are destroyed. Units' types are represented by letters; units' polarity is represented by capitalization. For instance, r and R are units with the same type but opposite polarity, whereas r and s are entirely different types and do not react. + +For example: + + In aA, a and A react, leaving nothing behind. + In abBA, bB destroys itself, leaving aA. As above, this then destroys itself, leaving nothing. + In abAB, no two adjacent units are of the same type, and so nothing happens. + In aabAAB, even though aa and AA are of the same type, their polarities match, and so nothing happens. + +Now, consider a larger example, dabAcCaCBAcCcaDA: + +dabAcCaCBAcCcaDA The first 'cC' is removed. +dabAaCBAcCcaDA This creates 'Aa', which is removed. +dabCBAcCcaDA Either 'cC' or 'Cc' are removed (the result is the same). +dabCBAcaDA No further actions can be taken. + +After all possible reactions, the resulting polymer contains 10 units. + +How many units remain after fully reacting the polymer you scanned? (Note: in this puzzle and others, the input is large; if you copy/paste your input, make sure you get the whole thing.) + +--- Part Two --- + +Time to improve the polymer. + +One of the unit types is causing problems; it's preventing the polymer from collapsing as much as it should. Your goal is to figure out which unit type is causing the most problems, remove all instances of it (regardless of polarity), fully react the remaining polymer, and measure its length. + +For example, again using the polymer dabAcCaCBAcCcaDA from above: + + Removing all A/a units produces dbcCCBcCcD. Fully reacting this polymer produces dbCBcD, which has length 6. + Removing all B/b units produces daAcCaCAcCcaDA. Fully reacting this polymer produces daCAcaDA, which has length 8. + Removing all C/c units produces dabAaBAaDA. Fully reacting this polymer produces daDA, which has length 4. + Removing all D/d units produces abAcCaCBAcCcaA. Fully reacting this polymer produces abCBAc, which has length 6. + +In this example, removing all C/c units was best, producing the answer 4. + +What is the length of the shortest polymer you can produce by removing all units of exactly one type and fully reacting the result? diff --git a/www/statics/aoc/2018/05_input.txt b/www/statics/aoc/2018/05_input.txt new file mode 100644 index

+The device on your wrist beeps several times, and once again you feel like you're falling. + +"Situation critical," the device announces. "Destination indeterminate. Chronal interference detected. Please specify new target coordinates." + +The device then produces a list of coordinates (your puzzle input). Are they places it thinks are safe or dangerous? It recommends you check manual page 729. The Elves did not give you a manual. + +If they're dangerous, maybe you can minimize the danger by finding the coordinate that gives the largest distance from the other points. + +Using only the Manhattan distance, determine the area around each coordinate by counting the number of integer X,Y locations that are closest to that coordinate (and aren't tied in distance to any other coordinate). + +Your goal is to find the size of the largest area that isn't infinite. For example, consider the following list of coordinates: + +1, 1 +1, 6 +8, 3 +3, 4 +5, 5 +8, 9 + +If we name these coordinates A through F, we can draw them on a grid, putting 0,0 at the top left: + +.......... +.A........ +.......... +........C. +...D...... +.....E.... +.B........ +.......... +.......... +........F. + +This view is partial - the actual grid extends infinitely in all directions.

However, the areas of coordinates D and E are finite: D is closest to 9 locations, and E is closest to 17 (both including the coordinate's location itself). Therefore, in this example, the size of the largest area is 17. + +What is the size of the largest area that isn't infinite? + +--- Part Two --- + +On the other hand, if the coordinates are safe, maybe the best you can do is try to find a region near as many coordinates as possible. + +For example, suppose you want the sum of the Manhattan distance to all of the coordinates to be less than 32.

+--- Day 9: Marble Mania --- + +You talk to the Elves while you wait for your navigation system to initialize. To pass the time, they introduce you to their favorite marble game. + +The Elves play this game by taking turns arranging the marbles in a circle according to very particular rules. The marbles are numbered starting with 0 and increasing by 1 until every marble has a number. + +First, the marble numbered 0 is placed in the circle. At this point, while it contains only a single marble, it is still a circle: the marble is both clockwise from itself and counter-clockwise from itself. This marble is designated the current marble. + +Then, each Elf takes a turn placing the lowest-numbered remaining marble into the circle between the marbles that are 1 and 2 marbles clockwise of the current marble. (When the circle is large enough, this means that there is one marble between the marble that was just placed and the current marble.) The marble that was just placed then becomes the current marble. + +However, if the marble that is about to be placed has a number which is a multiple of 23, something entirely different happens. First, the current player keeps the marble they would have placed, adding it to their score. In addition, the marble 7 marbles counter-clockwise from the current marble is removed from the circle and also added to the current player's score. The marble located immediately clockwise of the marble that was removed becomes the new current marble. + +For example, suppose there are 9 players. After the marble with value 0 is placed in the middle, each player (shown in square brackets) takes a turn. The result of each of those turns would produce circles of marbles like this, where clockwise is to the right and the resulting current marble is in parentheses: + +[-] (0) +[1] 0 (1) +[2] 0 (2) 1 +[3] 0 2 1 (3) +[4] 0 (4) 2 1 3 +[5] 0 4 2 (5) 1 3 +[6] 0 4 2 5 1 (6) 3 +[7] 0 4 2 5 1 6 3 (7) +[8] 0 (8) 4 2 5 1 6 3 7 +[9] 0 8 4 (9) 2 5 1 6 3 7 +[1] 0 8 4 9 2(10) 5 1 6 3 7 +[2] 0 8 4 9 2 10 5(11) 1 6 3 7 +[3] 0 8 4 9 2 10 5 11 1(12) 6 3 7 +[4] 0 8 4 9 2 10 5 11 1 12 6(13) 3 7 +[5] 0 8 4 9 2 10 5 11 1 12 6 13 3(14) 7 +[6] 0 8 4 9 2 10 5 11 1 12 6 13 3 14 7(15) +[7] 0(16) 8 4 9 2 10 5 11 1 12 6 13 3 14 7 15 +[8] 0 16 8(17) 4 9 2 10 5 11 1 12 6 13 3 14 7 15 +[9] 0 16 8 17 4(18) 9 2 10 5 11 1 12 6 13 3 14 7 15 +[1] 0 16 8 17 4 18 9(19) 2 10 5 11 1 12 6 13 3 14 7 15 +[2] 0 16 8 17 4 18 9 19 2(20)10 5 11 1 12 6 13 3 14 7 15 +[3] 0 16 8 17 4 18 9 19 2 20 10(21) 5 11 1 12 6 13 3 14 7 15 +[4] 0 16 8 17 4 18 9 19 2 20 10 21 5(22)11 1 12 6 13 3 14 7 15 +[5] 0 16 8 17 4 18(19) 2 20 10 21 5 22 11 1 12 6 13 3 14 7 15 +[6] 0 16 8 17 4 18 19 2(24)20 10 21 5 22 11 1 12 6 13 3 14 7 15 +[7] 0 16 8 17 4 18 19 2 24 20(25)10 21 5 22 11 1 12 6 13 3 14 7 15 + +The goal is to be the player with the highest score after the last marble is used up.

The Elves are very busy pushing things around in carts on some kind of rudimentary system of tracks they've come up with. + +Seeing as how cart-and-track systems don't appear in recorded history for another 1000 years, the Elves seem to be making this up as they go along. They haven't even figured out how to avoid collisions yet. + +You map out the tracks (your puzzle input) and see where you can help. + +Tracks consist of straight paths (| and -), curves (/ and \), and intersections (+). Curves connect exactly two perpendicular pieces of track; for example, this is a closed loop: + +/----\ +| | +| | +\----/ + +Intersections occur when two perpendicular paths cross. At an intersection, a cart is capable of turning left, turning right, or continuing straight. Here are two loops connected by two intersections: + +/-----\ +| | +| /--+--\ +| | | | +\--+--/ | + | | + \-----/ + +Several carts are also on the tracks. Carts always face either up (^), down (v), left (<), or right (>). (On your initial map, the track under each cart is a straight path matching the direction the cart is facing.) + +Each time a cart has the option to turn (by arriving at any intersection), it turns left the first time, goes straight the second time, turns right the third time, and then repeats those directions starting again with left the fourth time, straight the fifth time, and so on. This process is independent of the particular intersection at which the cart has arrived - that is, the cart has no per-intersection memory. + +Carts all move at the same speed; they take turns moving a single step at a time. They do this based on their current location: carts on the top row move first (acting from left to right), then carts on the second row move (again from left to right), then carts on the third row, and so on. Once each cart has moved one step, the process repeats; each of these loops is called a tick. + +For example, suppose there are two carts on a straight track: + +| | | | | +v | | | | +| v v | | +| | | v X +| | ^ ^ | +^ ^ | | | +| | | | | + +First, the top cart moves. It is facing down (v), so it moves down one square. Second, the bottom cart moves. It is facing up (^), so it moves up one square. Because all carts have moved, the first tick ends.

When you go to investigate, you discover two Elves in what appears to be a makeshift underground kitchen/laboratory. + +The Elves are trying to come up with the ultimate hot chocolate recipe; they're even maintaining a scoreboard which tracks the quality score (0-9) of each recipe. + +Only two recipes are on the board: the first recipe got a score of 3, the second, 7. Each of the two Elves has a current recipe: the first Elf starts with the first recipe, and the second Elf starts with the second recipe. + +To create new recipes, the two Elves combine their current recipes. This creates new recipes from the digits of the sum of the current recipes' scores. With the current recipes' scores of 3 and 7, their sum is 10, and so two new recipes would be created: the first with score 1 and the second with score 0. If the current recipes' scores were 2 and 3, the sum, 5, would only create one recipe (with a score of 5) with its single digit. + +The new recipes are added to the end of the scoreboard in the order they are created. So, after the first round, the scoreboard is 3, 7, 1, 0. + +After all new recipes are added to the scoreboard, each Elf picks a new current recipe. To do this, the Elf steps forward through the scoreboard a number of recipes equal to 1 plus the score of their current recipe. So, after the first round, the first Elf moves forward 1 + 3 = 4 times, while the second Elf moves forward 1 + 7 = 8 times. If they run out of recipes, they loop back around to the beginning. After the first round, both Elves happen to loop around until they land on the same recipe that they had in the beginning; in general, they will move to different recipes. + +Drawing the first Elf as parentheses and the second Elf as square brackets, they continue this process: + +(3)[7] +(3)[7] 1 0 + 3 7 1 [0](1) 0 + 3 7 1 0 [1] 0 (1) +(3) 7 1 0 1 0 [1] 2 + 3 7 1 0 (1) 0 1 2 [4] + 3 7 1 [0] 1 0 (1) 2 4 5 + 3 7 1 0 [1] 0 1 2 (4) 5 1 + 3 (7) 1 0 1 0 [1] 2 4 5 1 5 + 3 7 1 0 1 0 1 2 [4](5) 1 5 8 + 3 (7) 1 0 1 0 1 2 4 5 1 5 8 [9] + 3 7 1 0 1 0 1 [2] 4 (5) 1 5 8 9 1 6 + 3 7 1 0 1 0 1 2 4 5 [1] 5 8 9 1 (6) 7 + 3 7 1 0 (1) 0 1 2 4 5 1 5 [8] 9 1 6 7 7 + 3 7 [1] 0 1 0 (1) 2 4 5 1 5 8 9 1 6 7 7 9 + 3 7 1 0 [1] 0 1 2 (4) 5 1 5 8 9 1 6 7 7 9 2 + +The Elves think their skill will improve after making a few recipes (your puzzle input).

Looks like they're here for a fight. + +You scan the area, generating a map of the walls (#), open cavern (.), and starting position of every Goblin (G) and Elf (E) (your puzzle input). + +Combat proceeds in rounds; in each round, each unit that is still alive takes a turn, resolving all of its actions before the next unit's turn begins. On each unit's turn, it tries to move into range of an enemy (if it isn't already) and then attack (if it is in range). + +All units are very disciplined and always follow very strict combat rules. Units never move or attack diagonally, as doing so would be dishonorable. When multiple choices are equally valid, ties are broken in reading order: top-to-bottom, then left-to-right. For instance, the order in which units take their turns within a round is the reading order of their starting positions in that round, regardless of the type of unit or whether other units have moved after the round started. For example: + + would take their +These units: turns in this order: + ####### ####### + #.G.E.# #.1.2.# + #E.G.E# #3.4.5# + #.G.E.# #.6.7.# + ####### ####### + +Each unit begins its turn by identifying all possible targets (enemy units). If no targets remain, combat ends. + +Then, the unit identifies all of the open squares (.) that are in range of each target; these are the squares which are adjacent (immediately up, down, left, or right) to any target and which aren't already occupied by a wall or another unit. Alternatively, the unit might already be in range of a target. If the unit is not already in range of a target, and there are no open squares which are in range of a target, the unit ends its turn. + +If the unit is already in range of a target, it does not move, but continues its turn with an attack. Otherwise, since it is not in range of a target, it moves. + +To move, the unit first considers the squares that are in range and determines which of those squares it could reach in the fewest steps. A step is a single movement to any adjacent (immediately up, down, left, or right) open (.) square. Units cannot move into walls or other units. The unit does this while considering the current positions of units and does not do any prediction about where units will be later. If the unit cannot reach (find an open path to) any of the squares that are in range, it ends its turn. If multiple squares are in range and tied for being reachable in the fewest steps, the square which is first in reading order is chosen. For example: + +Targets: In range: Reachable: Nearest: Chosen: +####### ####### ####### ####### ####### +#E..G.# #E.?G?# #E.@G.# #E.!G.# #E.+G.# +#...#.# --> #.?.#?# --> #.@.#.# --> #.!.#.# --> #...#.# +#.G.#G# #?G?#G# #@G@#G# #!G.#G# #.G.#G# +####### ####### ####### ####### ####### + +In the above scenario, the Elf has three targets (the three Goblins): + + Each of the Goblins has open, adjacent squares which are in range (marked with a ? on the map). + Of those squares, four are reachable (marked @); the other two (on the right) would require moving through a wall or unit to reach. + Three of these reachable squares are nearest, requiring the fewest steps (only 2) to reach (marked !). + Of those, the square which is first in reading order is chosen (+). + +The unit then takes a single step toward the chosen square along the shortest path to that square. If multiple steps would put the unit equally closer to its destination, the unit chooses the step which is first in reading order. (This requires knowing when there is more than one shortest path so that you can consider the first step of each such path.) For example: + +In range: Nearest: Chosen: Distance: Step: +####### ####### ####### ####### ####### +#.E...# #.E...# #.E...# #4E212# #..E..# +#...?.# --> #...!.# --> #...+.# --> #32101# --> #.....# +#..?G?# #..!G.# #...G.# #432G2# #...G.# +####### ####### ####### ####### ####### + +The Elf sees three squares in range of a target (?), two of which are nearest (!), and so the first in reading order is chosen (+). Under "Distance", each open square is marked with its distance from the destination square; the two squares to which the Elf could move on this turn (down and to the right) are both equally good moves and would leave the Elf 2 steps from being in range of the Goblin. Because the step which is first in reading order is chosen, the Elf moves right one square. + +Here's a larger example of movement: + +Initially: +######### +#G..G..G# +#.......# +#.......# +#G..E..G# +#.......# +#.......# +#G..G..G# +######### + +After 1 round: +######### +#.G...G.# +#...G...# +#...E..G# +#.G.....# +#.......# +#G..G..G# +#.......# +######### + +After 2 rounds: +######### +#..G.G..# +#...G...# +#.G.E.G.# +#.......# +#G..G..G# +#.......# +#.......# +######### + +After 3 rounds: +######### +#.......# +#..GGG..# +#..GEG..# +#G..G...# +#......G# +#.......# +#.......# +######### + +Once the Goblins and Elf reach the positions above, they all are either in range of a target or cannot find any square in range of a target, and so none of the units can move until a unit dies. + +After moving (or if the unit began its turn in range of a target), the unit attacks. + +To attack, the unit first determines all of the targets that are in range of it by being immediately adjacent to it. If there are no such targets, the unit ends its turn. Otherwise, the adjacent target with the fewest hit points is selected; in a tie, the adjacent target with the fewest hit points which is first in reading order is selected. + +The unit deals damage equal to its attack power to the selected target, reducing its hit points by that amount. If this reduces its hit points to 0 or fewer, the selected target dies: its square becomes . and it takes no further turns. + +Each unit, either Goblin or Elf, has 3 attack power and starts with 200 hit points. + +For example, suppose the only Elf is about to attack: + + HP: HP: +G.... 9 G.... 9 +..G.. 4 ..G.. 4 +..EG. 2 --> ..E.. +..G.. 2 ..G.. 2 +...G. 1 ...G. 1 + +The "HP" column shows the hit points of the Goblin to the left in the corresponding row. The Elf is in range of three targets: the Goblin above it (with 4 hit points), the Goblin to its right (with 2 hit points), and the Goblin below it (also with 2 hit points). Because three targets are in range, the ones with the lowest hit points are selected: the two Goblins with 2 hit points each (one to the right of the Elf and one below the Elf). Of those, the Goblin first in reading order (the one to the right of the Elf) is selected. The selected Goblin's hit points (2) are reduced by the Elf's attack power (3), reducing its hit points to -1, killing it. + +After attacking, the unit's turn ends. Regardless of how the unit's turn ends, the next unit in the round takes its turn. If all units have taken turns in this round, the round ends, and a new round begins. + +The Elves look quite outnumbered. You need to determine the outcome of the battle: the number of full rounds that were completed (not counting the round in which combat ends) multiplied by the sum of the hit points of all remaining units at the moment combat ends.

You have a little while before you reach your next destination, and with a bit of trial and error, you manage to pull up a programming manual on the device's tiny screen. + +According to the manual, the device has four registers (numbered 0 through 3) that can be manipulated by instructions containing one of 16 opcodes. The registers start with the value 0. + +Every instruction consists of four values: an opcode, two inputs (named A and B), and an output (named C), in that order. The opcode specifies the behavior of the instruction and how the inputs are interpreted. The output, C, is always treated as a register. + +In the opcode descriptions below, if something says "value A", it means to take the number given as A literally. (This is also called an "immediate" value.) If something says "register A", it means to use the number given as A to read from (or write to) the register with that number. So, if the opcode addi adds register A and value B, storing the result in register C, and the instruction addi 0 7 3 is encountered, it would add 7 to the value contained by register 0 and store the sum in register 3, never modifying registers 0, 1, or 2 in the process. + +Many opcodes are similar except for how they interpret their arguments. The opcodes fall into seven general categories: + +Addition: + + addr (add register) stores into register C the result of adding register A and register B. + addi (add immediate) stores into register C the result of adding register A and value B. + +Multiplication: + + mulr (multiply register) stores into register C the result of multiplying register A and register B. + muli (multiply immediate) stores into register C the result of multiplying register A and value B. + +Bitwise AND: + + banr (bitwise AND register) stores into register C the result of the bitwise AND of register A and register B. + bani (bitwise AND immediate) stores into register C the result of the bitwise AND of register A and value B. + +Bitwise OR: + + borr (bitwise OR register) stores into register C the result of the bitwise OR of register A and register B. + bori (bitwise OR immediate) stores into register C the result of the bitwise OR of register A and value B. + +Assignment: + + setr (set register) copies the contents of register A into register C.

If it weren't for the coat you got in 1018, you would be very cold: the North Pole base hasn't even been constructed. + +Rather, it hasn't been constructed yet. The Elves are making a little progress, but there's not a lot of liquid water in this climate, so they're getting very dehydrated. Maybe there's more underground? + +You scan a two-dimensional vertical slice of the ground nearby and discover that it is mostly sand with veins of clay. The scan only provides data with a granularity of square meters, but it should be good enough to determine how much water is trapped there. In the scan, x represents the distance to the right, and y represents the distance down. There is also a spring of water near the surface at x=500, y=0. The scan identifies which square meters are clay (your puzzle input). + +For example, suppose your scan shows the following veins of clay: + +x=495, y=2..7 +y=7, x=495..501 +x=501, y=3..7 +x=498, y=2..4 +x=506, y=1..2 +x=498, y=10..13 +x=504, y=10..13 +y=13, x=498..504 + +Rendering clay as #, sand as ., and the water spring as +, and with x increasing to the right and y increasing downward, this becomes: + + 44444455555555 + 99999900000000 + 45678901234567 + 0 ......+....... + 1 ............#. + 2 .#..#.......#. + 3 .#..#..#...... + 4 .#..#..#...... + 5 .#.....#...... + 6 .#.....#...... + 7 .#######...... + 8 .............. + 9 .............. +10 ....#.....#... +11 ....#.....#... +12 ....#.....#... +13 ....#######... + +The spring of water will produce water forever. Water can move through sand, but is blocked by clay. Water always moves down when possible, and spreads to the left and right otherwise, filling space that has clay on both sides and falling out otherwise. + +For example, if five squares of water are created, they will flow downward until they reach the clay and settle there. Water that has come to rest is shown here as ~, while sand through which water has passed (but which is now dry again) is shown as |: + +......+....... +......|.....#. +.#..#.|.....#. +.#..#.|#...... +.#..#.|#...... +.#....|#...... +.#~~~~~#...... +.#######...... +.............. +.............. +....#.....#... +....#.....#... +....#.....#... +....#######... + +Two squares of water can't occupy the same location.

The device's manual goes on to explain: + +"In programs where flow control is required, the instruction pointer can be bound to a register so that it can be manipulated directly. This way, setr/seti can function as absolute jumps, addr/addi can function as relative jumps, and other opcodes can cause truly fascinating effects." + +This mechanism is achieved through a declaration like #ip 1, which would modify register 1 so that accesses to it let the program indirectly access the instruction pointer itself. To compensate for this kind of binding, there are now six registers (numbered 0 through 5); the five not bound to the instruction pointer behave as normal. Otherwise, the same rules apply as the last time you worked with this device. + +When the instruction pointer is bound to a register, its value is written to that register just before each instruction is executed, and the value of that register is written back to the instruction pointer immediately after each instruction finishes execution. Afterward, move to the next instruction by adding one to the instruction pointer, even if the value in the instruction pointer was just updated by an instruction. (Because of this, instructions must effectively set the instruction pointer to the instruction before the one they want executed next.) + +The instruction pointer is 0 during the first instruction, 1 during the second, and so on. If the instruction pointer ever causes the device to attempt to load an instruction outside the instructions defined in the program, the program instead immediately halts. The instruction pointer starts at 0. + +It turns out that this new information is already proving useful: the CPU in the device is not very powerful, and a background process is occupying most of its time. You dump the background process' declarations and instructions to a file (your puzzle input), making sure to use the names of the opcodes rather than the numbers. + +For example, suppose you have the following program: + +#ip 0 +seti 5 0 1 +seti 6 0 2 +addi 0 1 0 +addr 1 2 3 +setr 1 0 0 +seti 8 0 4 +seti 9 0 5 + +When executed, the following instructions are executed. Each line contains the value of the instruction pointer at the time the instruction started, the values of the six registers before executing the instructions (in square brackets), the instruction itself, and the values of the six registers after executing the instruction (also in square brackets). + +ip=0 [0, 0, 0, 0, 0, 0] seti 5 0 1 [0, 5, 0, 0, 0, 0] +ip=1 [1, 5, 0, 0, 0, 0] seti 6 0 2 [1, 5, 6, 0, 0, 0] +ip=2 [2, 5, 6, 0, 0, 0] addi 0 1 0 [3, 5, 6, 0, 0, 0] +ip=4 [4, 5, 6, 0, 0, 0] setr 1 0 0 [5, 5, 6, 0, 0, 0] +ip=6 [6, 5, 6, 0, 0, 0] seti 9 0 5 [6, 5, 6, 0, 0, 9] + +In detail, when running this program, the following events occur: + + The first line (#ip 0) indicates that the instruction pointer should be bound to register 0 in this program. This is not an instruction, and so the value of the instruction pointer does not change during the processing of this line. + The instruction pointer contains 0, and so the first instruction is executed (seti 5 0 1). It updates register 0 to the current instruction pointer value (0), sets register 1 to 5, sets the instruction pointer to the value of register 0 (which has no effect, as the instruction did not modify register 0), and then adds one to the instruction pointer. + The instruction pointer contains 1, and so the second instruction, seti 6 0 2, is executed. This is very similar to the instruction before it: 6 is stored in register 2, and the instruction pointer is left with the value 2. + The instruction pointer is 2, which points at the instruction addi 0 1 0. This is like a relative jump: the value of the instruction pointer, 2, is loaded into register 0. Then, addi finds the result of adding the value in register 0 and the value 1, storing the result, 3, back in register 0. Register 0 is then copied back to the instruction pointer, which will cause it to end up 1 larger than it would have otherwise and skip the next instruction (addr 1 2 3) entirely. Finally, 1 is added to the instruction pointer. + The instruction pointer is 4, so the instruction setr 1 0 0 is run. This is like an absolute jump: it copies the value contained in register 1, 5, into register 0, which causes it to end up in the instruction pointer. The instruction pointer is then incremented, leaving it at 6. + The instruction pointer is 6, so the instruction seti 9 0 5 stores 9 into register 5. The instruction pointer is incremented, causing it to point outside the program, and so the program ends. + +What value is left in register 0 when the background process halts? + +--- Part Two --- + +A new background process immediately spins up in its place.

When you look up, you discover that the North Pole base construction project has completely surrounded you. + +The area you are in is made up entirely of rooms and doors. The rooms are arranged in a grid, and rooms only connect to adjacent rooms when a door is present between them. + +For example, drawing rooms as ., walls as #, doors as | or -, your current position as X, and where north is up, the area you're in might look like this: + +##### +#.|.# +#-### +#.|X# +##### + +You get the attention of a passing construction Elf and ask for a map. "I don't have time to draw out a map of this place - it's huge. Instead, I can give you directions to every room in the facility!" He writes down some directions on a piece of parchment and runs off. In the example above, the instructions might have been ^WNE$, a regular expression or "regex" (your puzzle input). + +The regex matches routes (like WNE for "west, north, east") that will take you from your current room through various doors in the facility. In aggregate, the routes will take you through every door in the facility at least once; mapping out all of these routes will let you build a proper map and find your way around. + +^ and $ are at the beginning and end of your regex; these just mean that the regex doesn't match anything outside the routes it describes. (Specifically, ^ matches the start of the route, and $ matches the end of it.) These characters will not appear elsewhere in the regex. + +The rest of the regex matches various sequences of the characters N (north), S (south), E (east), and W (west). In the example above, ^WNE$ matches only one route, WNE, which means you can move west, then north, then east from your current position. Sequences of letters like this always match that exact route in the same order. + +Sometimes, the route can branch. A branch is given by a list of options separated by pipes (|) and wrapped in parentheses. So, ^N(E|W)N$ contains a branch: after going north, you must choose to go either east or west before finishing your route by going north again. By tracing out the possible routes after branching, you can determine where the doors are and, therefore, where the rooms are in the facility. + +For example, consider this regex: ^ENWWW(NEEE|SSE(EE|N))$ + +This regex begins with ENWWW, which means that from your current position, all routes must begin by moving east, north, and then west three times, in that order. After this, there is a branch. Before you consider the branch, this is what you know about the map so far, with doors you aren't sure about marked with a ?: + +#?#?#?#?# +?.|.|.|.? +#?#?#?#-# + ?X|.? + #?#?# + +After this point, there is (NEEE|SSE(EE|N)). This gives you exactly two options: NEEE and SSE(EE|N). By following NEEE, the map now looks like this: + +#?#?#?#?# +?.|.|.|.? +#-#?#?#?# +?.|.|.|.? +#?#?#?#-# + ?X|.? + #?#?# + +Now, only SSE(EE|N) remains. Because it is in the same parenthesized group as NEEE, it starts from the same room NEEE started in. It states that starting from that point, there exist doors which will allow you to move south twice, then east; this ends up at another branch. After that, you can either move east twice or north once. This information fills in the rest of the doors: + +#?#?#?#?# +?.|.|.|.? +#-#?#?#?# +?.|.|.|.? +#-#?#?#-# +?.?.?X|.? +#-#-#?#?# +?.|.|.|.? +#?#?#?#?# + +Once you've followed all possible routes, you know the remaining unknown parts are all walls, producing a finished map of the facility: + +######### +#.|.|.|.# +#-####### +#.|.|.|.# +#-#####-# +#.#.#X|.# +#-#-##### +#.|.|.|.# +######### + +Sometimes, a list of options can have an empty option, like (NEWS|WNSE|). This means that routes at this point could effectively skip the options in parentheses and move on immediately. For example, consider this regex and the corresponding map: + +^ENNWSWW(NEWS|)SSSEEN(WNSE|)EE(SWEN|)NNN$ + +########### +#.|.#.|.#.# +#-###-#-#-# +#.|.|.#.#.# +#-#####-#-# +#.#.#X|.#.# +#-#-#####-# +#.#.|.|.|.# +#-###-###-# +#.|.|.#.|.# +########### + +This regex has one main route which, at three locations, can optionally include additional detours and be valid: (NEWS|), (WNSE|), and (SWEN|). Regardless of which option is taken, the route continues from the position it is left at after taking those steps. So, for example, this regex matches all of the following routes (and more that aren't listed here): + + ENNWSWWSSSEENEENNN + ENNWSWWNEWSSSSEENEENNN + ENNWSWWNEWSSSSEENEESWENNNN + ENNWSWWSSSEENWNSEEENNN + +By following the various routes the regex matches, a full map of all of the doors and rooms in the facility can be assembled. + +To get a sense for the size of this facility, you'd like to determine which room is furthest from you: specifically, you would like to find the room for which the shortest path to that room would require passing through the most doors. + + In the first example (^WNE$), this would be the north-east corner 3 doors away. + In the second example (^ENWWW(NEEE|SSE(EE|N))$), this would be the south-east corner 10 doors away. + In the third example (^ENNWSWW(NEWS|)SSSEEN(WNSE|)EE(SWEN|)NNN$), this would be the north-east corner 18 doors away. + +Here are a few more examples: + +Regex: ^ESSWWN(E|NNENN(EESS(WNSE|)SSS|WWWSSSSE(SW|NNNE)))$ +Furthest room requires passing 23 doors + +############# +#.|.|.|.|.|.# +#-#####-###-# +#.#.|.#.#.#.# +#-#-###-#-#-# +#.#.#.|.#.|.# +#-#-#-#####-# +#.#.#.#X|.#.# +#-#-#-###-#-# +#.|.#.|.#.#.# +###-#-###-#-# +#.|.#.|.|.#.# +############# + +Regex: ^WSSEESWWWNW(S|NENNEEEENN(ESSSSW(NWSW|SSEN)|WSWWN(E|WWS(E|SS))))$ +Furthest room requires passing 31 doors + +############### +#.|.|.|.#.|.|.# +#-###-###-#-#-# +#.|.#.|.|.#.#.# +#-#########-#-# +#.#.|.|.|.|.#.# +#-#-#########-# +#.#.#.|X#.|.#.# +###-#-###-#-#-# +#.|.#.#.|.#.|.# +#-###-#####-### +#.|.#.|.|.#.#.# +#-#-#####-#-#-# +#.#.|.|.|.#.|.# +############### + +What is the largest number of doors you would be required to pass through to reach a room?

Instead, he offers you some milk and cookies. + +After talking for a while, he asks a favor of you. His friend hasn't come back in a few hours, and he's not sure where he is. Scanning the region briefly, you discover one life signal in a cave system nearby; his friend must have taken shelter there. The man asks if you can go there to retrieve his friend. + +The cave is divided into square regions which are either dominantly rocky, narrow, or wet (called its type). Each region occupies exactly one coordinate in X,Y format where X and Y are integers and zero or greater. (Adjacent regions can be the same type.) + +The scan (your puzzle input) is not very detailed: it only reveals the depth of the cave system and the coordinates of the target. However, it does not reveal the type of each region. The mouth of the cave is at 0,0. + +The man explains that due to the unusual geology in the area, there is a method to determine any region's type based on its erosion level. The erosion level of a region can be determined from its geologic index. The geologic index can be determined using the first rule that applies from the list below: + + The region at 0,0 (the mouth of the cave) has a geologic index of 0. + The region at the coordinates of the target has a geologic index of 0. + If the region's Y coordinate is 0, the geologic index is its X coordinate times 16807. + If the region's X coordinate is 0, the geologic index is its Y coordinate times 48271. + Otherwise, the region's geologic index is the result of multiplying the erosion levels of the regions at X-1,Y and X,Y-1. + +A region's erosion level is its geologic index plus the cave system's depth, all modulo 20183. Then: + + If the erosion level modulo 3 is 0, the region's type is rocky. + If the erosion level modulo 3 is 1, the region's type is wet. + If the erosion level modulo 3 is 2, the region's type is narrow. + +For example, suppose the cave system's depth is 510 and the target's coordinates are 10,10. Using % to represent the modulo operator, the cavern would look as follows: + + At 0,0, the geologic index is 0. The erosion level is (0 + 510) % 20183 = 510. The type is 510 % 3 = 0, rocky. + At 1,0, because the Y coordinate is 0, the geologic index is 1 * 16807 = 16807. The erosion level is (16807 + 510) % 20183 = 17317. The type is 17317 % 3 = 1, wet. + At 0,1, because the X coordinate is 0, the geologic index is 1 * 48271 = 48271. The erosion level is (48271 + 510) % 20183 = 8415. The type is 8415 % 3 = 0, rocky. + At 1,1, neither coordinate is 0 and it is not the coordinate of the target, so the geologic index is the erosion level of 0,1 (8415) times the erosion level of 1,0 (17317), 8415 * 17317 = 145722555. The erosion level is (145722555 + 510) % 20183 = 1805. The type is 1805 % 3 = 2, narrow. + At 10,10, because they are the target's coordinates, the geologic index is 0. The erosion level is (0 + 510) % 20183 = 510. The type is 510 % 3 = 0, rocky. + +Drawing this same cave system with rocky as ., wet as =, narrow as |, the mouth as M, the target as T, with 0,0 in the top-left corner, X increasing to the right, and Y increasing downward, the top-left corner of the map looks like this: + +M=.|=.|.|=.|=|=. +.|=|=|||..|.=... +.==|....||=..|== +=.|....|.==.|==. +=|..==...=.|==.. +=||.=.=||=|=..|= +|.=.===|||..=..| +|..==||=.|==|=== +.=..===..=|.|||. +.======|||=|=.|= +.===|=|===T===|| +=|||...|==..|=.| +=.=|=.=..=.||==| +||=|=...|==.=|== +|=.=||===.|||=== +||.|==.|.|.||=|| + +Before you go in, you should determine the risk level of the area.

You cannot use the torch (if it gets wet, you won't have a light source). + In narrow regions, you can use the torch or neither tool. You cannot use the climbing gear (it's too bulky to fit). + +You start at 0,0 (the mouth of the cave) with the torch equipped and must reach the target coordinates as quickly as possible. The regions with negative X or Y are solid rock and cannot be traversed. The fastest route might involve entering regions beyond the X or Y coordinate of the target. + +You can move to an adjacent region (up, down, left, or right; never diagonally) if your currently equipped tool allows you to enter that region. Moving to an adjacent region takes one minute. (For example, if you have the torch equipped, you can move between rocky and narrow regions, but cannot enter wet regions.) + +You can change your currently equipped tool or put both away if your new equipment would be valid for your current region.

He seems relieved to see his friend, but quickly notices that the little reindeer caught some kind of cold while out exploring. + +The portly man explains that this reindeer's immune system isn't similar to regular reindeer immune systems: + +The immune system and the infection each have an army made up of several groups; each group consists of one or more identical units. The armies repeatedly fight until only one army has units remaining. + +Units within a group all have the same hit points (amount of damage a unit can take before it is destroyed), attack damage (the amount of damage each unit deals), an attack type, an initiative (higher initiative units attack first and win ties), and sometimes weaknesses or immunities. Here is an example group: + +18 units each with 729 hit points (weak to fire; immune to cold, slashing) + with an attack that does 8 radiation damage at initiative 10 + +Each group also has an effective power: the number of units in that group multiplied by their attack damage. The above group has an effective power of 18 * 8 = 144. Groups never have zero or negative units; instead, the group is removed from combat. + +Each fight consists of two phases: target selection and attacking. + +During the target selection phase, each group attempts to choose one target. In decreasing order of effective power, groups choose their targets; in a tie, the group with the higher initiative chooses first. The attacking group chooses to target the group in the enemy army to which it would deal the most damage (after accounting for weaknesses and immunities, but not accounting for whether the defending group has enough units to actually receive all of that damage). + +If an attacking group is considering two defending groups to which it would deal equal damage, it chooses to target the defending group with the largest effective power; if there is still a tie, it chooses the defending group with the highest initiative. If it cannot deal any defending groups damage, it does not choose a target. Defending groups can only be chosen as a target by one attacking group. + +At the end of the target selection phase, each group has selected zero or one groups to attack, and each group is being attacked by zero or one groups. + +During the attacking phase, each group deals damage to the target it selected, if any. Groups attack in decreasing order of initiative, regardless of whether they are part of the infection or the immune system. (If a group contains no units, it cannot attack.) + +The damage an attacking group deals to a defending group depends on the attacking group's attack type and the defending group's immunities and weaknesses. By default, an attacking group would deal damage equal to its effective power to the defending group. However, if the defending group is immune to the attacking group's attack type, the defending group instead takes no damage; if the defending group is weak to the attacking group's attack type, the defending group instead takes double damage. + +The defending group only loses whole units from damage; damage is always dealt in such a way that it kills the most units possible, and any remaining damage to a unit that does not immediately kill it is ignored. For example, if a defending group contains 10 units with 10 hit points each and receives 75 damage, it loses exactly 7 units and is left with 3 units at full health. + +After the fight is over, if both armies still contain units, a new fight begins; combat only ends once one army has lost all of its units. + +For example, consider the following armies: + +Immune System: +17 units each with 5390 hit points (weak to radiation, bludgeoning) with + an attack that does 4507 fire damage at initiative 2 +989 units each with 1274 hit points (immune to fire;

You suspect the reindeer has never encountered hot chocolate before, but seems to enjoy it anyway. You hope it works. + +It's time to start worrying about that integer underflow in time itself you set up a few days ago.
