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.

Wow, that's good to know. Thanks for the info.
not possible anymore (ranks cannot be changed after approval. At least, thses days...)
This problem feels more difficult than other "8 kyu" problems. I'd suggest making it at least "7 kyu".
If someone doesn't use sort, the problem is even more difficult.
Can you incorporate the JS language into kata?
