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.
I really don't see how this is a kata issue; your solution passes, and even if it didn't, it wouldn't be a kata problem.
If you really think this is an issue, please elaborate; however, I'm closing this for now.
