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.
Kicking myself for not doing this now...

I loved this Kata! Thanks for the challenge :)
That is true but the only difference it would make in most of these solutions would be a conditional to check if the element being iterated on contains non-characters,
in which case a simple regex would solve the problem. So I wouldn't consider it that big of an issue.

Kind of user dependant. I personally struggled very hard with the "Squares in a Rectangle" 6 kyu, and would consider that MUCH harder than this.
BUT, I'm sure there are plenty who feel the exact opposite.
This was an awesome Kata, thank you for the challenge!
