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.

Could you solve it?
My code works for 50 tests. I tried numbers, special characters and of course upper and lower cases. My test runs perfect, but i get a timeout if I submit. Im pretty sure my code works.
I think you can use the square root as limit for the for function that would reduce the numbers to check. To further improve performance we could start at 1 and do doublejumps and do the 2 separately
