Didn't realize that. But in any case, I tried the kata again and the solution passed in 74ms.
So, it's definitely possible to do this kata.

I don't think that the Code Runner is not running up to speed.

Have a look at it here:

I got it!!!!

Thank you Sir Crazy., I'd basically given up on it yesterday thinking my old laptop just couldn't do the addition.

No, it means that your algorithms is too slow. You need to optimize your program. Maybe think of a better way to solve the problem.

If I get a error of:

Process terminated, took too long to complete (6000ms)

Could it be that my personal machine just can't go through all the random tests fast enough to count as complete?
