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'm learning and I have a question, If 'str' is empty, it returns null and should return []. How does the test pass?
It's a great solution
Mindblowing
good idea!!
...in spite of it being patched by the author.
This is amazing
this solution gonna return null if the str is empty, but the expected is[]
