By replacing each of the letters in the word CARE with 1, 2, 9, and 6 respectively,
|
||
|
|
we form a square number: 1296 = 36^2. What is remarkable is that,
|
||
|
|
by using the same digital substitutions, the anagram, RACE,
|
||
|
|
also forms a square number: 9216 = 96^2.
|
||
|
|
We shall call CARE (and RACE) a square anagram word pair and specify further
|
||
|
|
that leading zeroes are not permitted,
|
||
|
|
neither may a different letter have the same digital value as another letter.

Using [words.txt](https://projecteuler.net/project/resources/p098_words.txt),
|
||
|
|
a 16K text file containing nearly two-thousand common English words,
|
||
|
|
find all the square anagram word pairs
|
||
|
|
(a palindromic word is NOT considered to be an anagram of itself).
|
||
|
|
|
||
|
|
What is the largest square number formed by any member of such a pair?
|
||
|
|
|
||
|
|
NOTE: All anagrams formed must be contained in the given text file.
