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.
You should add random test cases to avoid hard coded solutions.
issue part:
suggestion part:
Since your kata has a so low satisfaction rate that there are almost no chances it goes out of beta and that other kata exists with the same (approximately) task to do, I'd suggest you unpublish this one and publish a translation of the one that is the most similar from the two above. But if the author isn't active anymore, you'll need a moderator to "hard copy" your translation directly in the edit panel (but note that you won't recieve honor/% progress, this way, unfortunately).
