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 am worried but 5 guys passed the kata, it's not that much (but for Ocaml not that bad since not many guys practice Ocaml at CW). I tried several solutions and all worked fine. The Ocaml translation was validated without any problem.
Nevertheless I slightly modified the "Submit" tests and your solution should pass now. Please tell me if it works now.
