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.

It's a nice kata (and for 6kyu maybe even a bit too easy), but the example where part of the input array is 0.55 is quite misleading - int in c# cannot have a decimal value.
