Regrettably your solution is not efficient enough to perform well with big numbers; I would try another approach ;)

Has it been like this for a while? There was a time some time ago where the linking was broken. Try unlinking your github and then linking it again.

Giving more thought about this.

on number 1: do you mean as a solution setup so they just fill in the blanks?

I think its better that you get to build your own function.

1. Okey.
2. Sure I can add more test cases.
3. Yes I could do that. But the idea was just to append to a global array. But thinking about it I might evolve it to that.

Thanks for the input this is my first kata :-)
