"""Codewars: Multiples of 3 or 5
6 kyu

URL: https://www.codewars.com/kata/514b92a657cdc65150000006/

If we list all the natural numbers below 10 that are multiples of 3 or 5,
we get 3, 5, 6 and 9. The sum of these multiples is 23.

Finish the solution so that it returns the sum of all the multiples of 3 or 5
below the number passed in.

Note: If the number is a multiple of both 3 and 5, only count it once.
