Lol. I have no idea what that was about. It worked because that if statement always evaluates to true. I probably meant if(end >= start), but that isn't necessary either: the for loop should be good enough without the if statement. So that's a bit of a mystery to me. This code was from many years ago, and I no longer remember what I was thinking.

Not a great Kata as I believe most schools/universities round up scoring to avoid arguments whereas this Kata rounds down by using int divison

What happens after 2099???????
