* Fix style of the first ten solutions for Project Euler - Unify the header docstring, and add reference URLs to wikipedia or similar - Fix docstrings to be properly multilined - Add newlines where appropriate - Add doctests where they were missing - Remove doctests that test for the correct solution - fix obvious spelling or grammar mistakes in comments and exception messages - Fix line endings to be UNIX. This makes two of the files seem to have changed completely - no functional changes in any of the solutions were done (except for the spelling fixes mentioned above) * Fix docstrings and main function as per Style Guide

Multiples of 3 and 5
|
|
|
|
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.
|
|
|
|
Find the sum of all the multiples of 3 or 5 below 1000.
