Loading collection data...
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.
Get started now by creating a new collection.
I don't know Haskell, so I cannot speak to that translation, but such a test case already exists in all other languages.
thanks for the advice!
Note to self: I should have added the edge case in the test when I translated the kata.
