Comparing two numbers written in index form like 2^11 and 3^7 is not difficult, as any calculator would confirm that 2^11 = 2048 < 3^7 = 2187. However, confirming that 632382^518061 > 519432^525806 would be much more difficult, as both numbers contain over three million digits. Using [base_exp.txt](https://projecteuler.net/project/resources/p099_base_exp.txt), a 22K text file containing one thousand lines with a base/exponent pair on each line, determine which line number has the greatest numerical value. NOTE: The first two lines in the file represent the numbers in the example given above.
