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.

I agree with you. Took me 10 mins to figure out what the task was.. But we get real life problems unclear as this :)
Exactly
I didn't realize that people may not think about that. I've tried to clearify that in the description now. If there's something else that can easily be missunderstood, just tell me and I'll add it too.
Plus one.
And what does it mean "except for Haskell"?
I made the exact same mistake. The description does not mention order is important. I was left thinking that maybe
Xshould map toXif it existed inb, but could map to something else if not. That wasn't it either. Then I read the comments, and discovered the actual intent of the kata.All this might be in the definition of "isomorphic". But I don't know that. I think the kata would be better if the conditions were explained better.
That's not an issue, that's a question.
Also, order is important.
