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.
thank you
This is an issue with your code, not the kata. Your code is wrong. "11 should equal 5" means that your code returned 11, but the correct answer that it should have returned is 5. The original input is not included in the error message.
11 should equal 5. Wat??? it's 2. Who can fix this test?
