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.

how does this work? I am confused by the if statement. Why do you not need to match the toy key to the number and then reduce the number by the amount of the key?
Thanks Alyona42
