Problem:
|
||
|
|
|
||
|
|
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 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.
