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.
Edit: nevermind, I made this wayyyy too difficult hahaha.

Your solution doesn't really make sense. You don't check string lengths (in general) to check a number's property the same way you don't check whether your cat is on fire by talking to a psychologist.
Try a different approach.
