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.

Yeah, it worked in the end. Turns out the server has been timing out a lot of katas recently. Nothing wrong with the kata itself.
I keep getting "submission timed out" no matter what I do. Even a function consisting solely of a pass or return [1, 2] times out. This is for both the test cases and final solution.
