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.

Error: "not all code paths return a value". My code works fine in another compiler with same sample tests. What does it mean?
Same, I passed all of random tests, but one of test1 was wrong. I don't know the input, so I don't know why it didn't work.
