diotalevi,
You're probably right about people in general not having a clue as to the right approach without reading the spoilers. I am an avid puzzle and riddle aficionado. One kind of puzzle I see is identifying someone's ATM PIN using a constrained version of this. I incorrectly assumed people who enjoyed my challenges to have the same kind of exposure and recognize it as being similar :-(

The more interesting problem to me is the general case which I am hoping someone provides a better solution then my own.

Thanks for your regex solution. I am not sure I understand it but it gives me something new to work at learning.

Cheers - L~R
