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.
Thanks for the suggestion.
Hi, my solution passes all the tests except one: the first item. Here, it says that "1 should equal 0".
I find this description very vague. First item of what, the input array?
I would like some feedback, please.
PS: I wrote the solution in Python.
