Maybe

Agreed. It's a good Kata, but definitely not a 4. Way to easy for 4.

@ineti - your 8 kyu Haskell kata are finally here!

I am so upvoting this comment! On my machine my script works excellent upon many tests, but here...

when I hit the "compare" to my solution button I only see part of my submitted code?

I suggest reading the rest of these comments and updating the description further. Currently it's dificult to understand that you're looking to break a large array of 6+ people into the seperate floors they are on.

I think the lessoned to be learned here is that kata autors should include helpful failure messages when writing tests cases. It's trivial to do this, and supported by the current test framework, so I'm not sure why you're saying that you need to wait on the "fork" system.

I'm not sure about different ranks for different languages and the same problem.

Isn't it a case of logical solution, and use the tools that the language provides?

It's just that I don't see how it should be harder in different languages, i might need to implement some more things, but the logic would be similar.

Just my opinion though :)

The "hash._key=" bit really threw me off, because I had assumed to perform an assignment only if arguments were present (which would work)

Agreed, there needs to be more clarification about these cases since either direction could make sense and thus causes ambiguity.

Now using two block in stead of one has just gotten me really confused. I'd prefer switching back to just one or using two different chars that could add up to look like a cell in stead, like "[]".

I definitely want an easier way to find out when my solutions have been invalidated — this would help during beta testing. (Plus, it would be nice to have a list of all my invalidated solutions in one place...)

So I'm probably just being lazy but it would be nice to have a sample card set + solution provided as a test in the JS version. Other than that great kata!

Since the description defines a prime as greater than 1, I hope it's clear that 1 should not be included. Let me know if you have suggestions for the description.
