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.
Thats was an interesting kata! Just after my attempt passed thrught all the test I noticed that it could be solved much easier, even without looping. (Rust )
Thanks for this kata. This type of challange is suprisingly funny.
