Maybe we have a different hiring mindset than dschoon - we're equally happy with people who find the answers or create the answers. In a production system, we certainly wouldn't want hand-rolled primeness checking. But in a programming challenge, we think it's fun to write it for yourself.

Oops; I wrote my comment under the assumption that dschoon was with greplin, and in retrospect I'm not sure why. Sorry about that.
