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.
I'm facing the same issue haha
Encounter the same problem, and thanks for higlighting the test case which I couldn't find. I finally solved this kata just adding one little trick. Rethink some terms and good luck.

I have the same problem, it says "3 should equal 4". The rest is correct. It is not clear what the input is to check my mistake.
