Something I found the other day, some people seem to be under the impression
that you guys would enjoy it, so here goes.
Take a number, generate a string that contains that many "1"s
Match it against the following regex:
/^1?$|^(11+?)\1+$/
If it fails to match, you sir (or madam), have yourself a PRIME number.
Enjoy :)
