What about 0 or negative numbers? There is a maximum value for the input or anything like
21234567890212345678902123456789021234567890212345678902123456789045678902123456789456789034562123021234567890

I am wondering how many people do these challenges on the dpcdev.com site. I tend to be on the leader board waaay too easily. Maybe the leader-board does not quite work? Anyway, I encourage everyone to try. The tasks are relatively simple, take 5-10 minutes. A coffee break thing.
