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.
Both tests are fine, not a kata issue.
Your code not working is not an issue (an issue is a bug in the kata). Please read this: https://docs.codewars.com/training/troubleshooting
Your code crashes in sample tests too (third test), try to figure out why.
Please use markdown format tags to format your code, or it's quite unreadable and unusable, as explained there: https://docs.codewars.com/training/troubleshooting/#post-discourse
