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.

Hello, DegaKiller! I don't know what your specific case is, but note that in some tests, pin = "123\n" or "1234\n" (line break, not space). I got caught on this and also thought it was a bug.
Can someone explain to me why this method has a "string" return type, but after "return" we see "long" and it all works. For what we need this "long"?
