Cheers people

I tried both of them first with a single figured number, and they both worked fine.
I then tried with 20000000000000000000 just for the hell of it. Colins code said this was uneven, while Tektons said even.
Then I tried with 20000000000000000001 which reversedly Colins code called uneven, while Tektons called it even.
Now I dont need such a high number, just 100 or so. And they both say thats even XD
Thanks again guys
