Done for Ruby.

... You should repeat both of the following steps together until the original string length is less than 2 ...

Done in this fork

I just changed the behaviour of Haskell to match JS and Python. Ruby still needs to be adjusted.

Python fork rewriting the description & adding fixed tests of string length (0 - 2)

Yes, that was not clearly specifified and could only be derived from the example. To make sense as an outlier-rejection algorithm the order of evaluation must not matter. We therefore only consider the original data as a whole.

Thank you for the feedback on the beta of this Kata! The initical code was indeed necessary as part of the specification, so I changed the description now that it can stand alone.

Thank you for the suggestion. I removed the "for simplicity" from the description. Please do not hesitate to give any additonal feedback.

Of course, my friend. I'm sorry for the carelessness

I've even approved a translation on that one, haha! I'll "retire" this kata.

I think it's a unique enough problem without those hints.

Gah, fixed! ;-)

Good point, I've added a relevant example in the Kata description and sample tests and mentioned that the digit should be returned "as an integer".
