I tried to solve it with recursion, which I got some errors because it is reached recursion depth. So, you guys now that there is a constraint on using recursion approach. Test cases should actually be until it reaches the stack limit.

In what language? What exactly is wrong with the tests?

Looks like some test cases doesn't work anymore or doesn't check properly.
Even looking into solution and trying to paste the solution, returns an error. Unfortunately.

I think this is what it is supposed to be, not int(string)

I didn't understand this though. Can someone clarify it please? Or direct to the documentation.

Exeding execution time, on my local it works perfect.

Language and input?

Facing same issue.

It's not bugged, you can try my code (follows hidden) - i think i know the problem of these solutions, it's not an issue of kata;-)...

Down they say it is bugged: can you confirm it is not?

You can fix the kata with my solution code? But there's nothing to fix, the kata works for c#?! Don't know the problem here?

If you want to pass me the code, I can fix it :)

Just wrote a c# solution for testing, but now i see that i can't edit your kata:-( "Looks like there was a server error! (500)"
Seems to me that everything is ok with the c# version or what's the problem here?
