For Project 16 of Project Euler, I’ll jump over to Ruby for an elegant solution.

## Problem 16:

### Power Digit Sum

2^15 = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.

What is the sum of the digits of the number 2^1000?

To come to this solution, we generate the result of 2^1000, convert it into a string and split each digit into its own entry on an array, then sum them up all in one easy line.

answer = (2**1000).to_s.split('').map(&:to_i).reduce(:+) puts answer --output: 1366
