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.

Nice catch! Fixed.
You are very persistent :)
To be honest, there is not much fun going back to a problem because it had a weak test case to begin with. Anyway, I have updated the solution.

Use spoiler flag, please.
First, note I don't do Haskell, but anything inside quotes is a valid string afaik. In the kata description that input is an integer instead. It doesn't seem you can send different types as input in Haskell (with the function defined as it is right now), like you can do with loosely typed languages as javascript. I don't know how to solve this, I'll leave it to other people then.
I fail to see how
"1234"is not a string. Did you mean?
