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.

Your code is too slow, it doesn't fail on the last number, it just times out at some point. You need to do it another way, this is a 3kyu so you should expect some advanced stuff or trick is required. And this is not a kata suggestion (=suggestion of improvement for the kata).
