Project Euler : Considering natural numbers of the form, ab, finding the maximum digital sum.

Problem 56

A googol (10¹⁰⁰) is a massive number: one followed by one-hundred zeros; 100¹⁰⁰ is almost unimaginably large: one followed by two-hundred zeros. Despite their size, the sum of the digits in each number is only 1.
Considering natural numbers of the form, a^b, where a, b < 100, what is the maximum digital sum?

Solution (in Ruby)

Nothing much to discuss about the solution, I've implemented it directly as given in the problem statement.
