I already have updated the description but when it is not yet clear enough I'll try again :) thx for the feedback. In the meantime, you can go trough a blog post which I have created about this topic here but careful, if you don't wan't to spoil yourself, at the end is a solution in go which could be used in this kata.

Thx, I have thought about that. Now I am going to change that for all languages :)

Thx, I didn't think about that, there is already a solution which only satisfies the test cases ^^ I'll implement some random tests :)

Yes mabye I should be more specific about that. Thx I'll consider your input at the next correction.

thx for the feed back, I'll correct the code :)

It was fun but hart :D I'd say it would better fit in the 4kyu section :)
