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.
ah ha! wow - nice kata. If anyone wants a really vague hint, the solution is like rubbing your head while patting your belly.

Any plans for codewars to update to 1.53 so my answer can compile? :D
yes, it is not needed - explicit vs implicit choice.
Thank you @Chrono79 -- that makes sense why I was confused.
Relax hobo, please be kind, world is already an ugly place.

and google calculator says 30! = 2.65252859812e+32
calculator soup must have something else going on. Agree with others though, little too mathy on this one for my tastes.

I had a similar moment @crosssh, the test cases are a little ambiguous, if you comment out the first test case and remove your join you will see what is going on.
Yea I realize it's pretty easy to just edit them with individual it statements, not used to being able to edit the test cases. Codewars really does a good job.
Would be nice if all tests showed outputs and not just the first failure. Took me a minute to realize that the error I was dealing with was on the second test, not the first.
