**Largest exponential**

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 , a text file containing one thousand lines with a base/exponent pair on each line, determine which line number has the greatest numerical value.
