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.
Well I got that one wrong for sure.
Yeah I misunderstood the requirements.
That makes sense. They should make that clear, however.
Probably doesn't require the brackets. I also reasoned that if this code were to end up in production it helps to have the steps laid out even if it's obvious.
If any of the constraints fail then the whole solution should return None.
This is the first correct answer I've seen! The test constraints on this Kata are obviously broken.
This is the third incorrect solution at the top of this page. This kata is not very good.
This is also incorrect. Needs to take constraints into account.
This is incorrect.
oh my poor eyes!
