Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I'm assuming in Python 2, 9/4 = 2, but 9.0/4.0 = 2.25.
wait what? then how did Python 2 divide normally?
Huh? Surely it doesn't work, as it doesn't return an integer. Am I missing something?
Another solution with O(n^2) complexity. Very inelegant.
This is terrible, it has O(n^2) complexity.
