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.
Let me disagree. All you need to do is to first think about what the kata actually wants you to do. And then write a non-complex solution like other 6 kyu kata.
Not a kata issue, your function is returning a list instead of a number.
