I didn't give much thought before posting as issue, what I meant was "I have an issue with the code, do you know why". Last time I posted somewhere else as question and the post got hidden without an answer so I thought the tag was wrong.
Thanks either way.

I didn't say the kata or the test is wrong, I'm asking what the problem is.
I have done tests and it works, that's why I asked. You could have minded your own business if you didn't want to help.
