I agree to Dentzil. This is no issue.

The author or Maksim should close it!

Hi Maksim,

Why did you mark it as issue?

Are you sure, that 'long' will be enough for the following test input: for example a = 1, b = 900?

I think this Issue is already fixed, I request author or MaksimSimkim to mark this as resolved otherwise this kata will not be able to come out of beta.

Apart from that I must say this is a nice beginner kata ^_^ I'll try to translate it into Javascript.

I see exactly what you're saying; that's an awful oversight on my part.

Thanks a lot for explaining. I've updated the default, would you mind checking?

Thanks again.

I think he means the same issue I was having below that you marked as resolved, but it is not.
The default "Your solution" you start with is like this:

public static int AddStrings(string numbers)
{
// Hack the planet!
}

You can not compile it (Run Tests / Submit), as it is not part of a class, you have to manually add it like this:
public static class StringCalculator
{
public static int AddStrings(string numbers)
{
// Hack the planet!
return 0; //just return something so that it will compile
}
}

Could you explain further please? Thanks

Thanks! i'll add it right now!
