Thanks. I transferred this over from my Java implementation of it and didn't quite get it right, so I did some stuff to make it work. You helped me get it back to what it was originally. Not too confident in the one-line generator you have there, but it'd be a nice touch anyway.

    Why? Don't you trust mathematics?

    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

      I trust the math of it. It's not that I'm not confident that grizzley's solution is mathematically sound. Rather, I'm not confident in my own ability to fully understand that use of map, especially if I were to stop thinking about this and come back to it later. I also don't really see the need.

        Come back here regularly, participate in helping others and soon map and other useful Perl-constructs will have no secrets for you anymore. Your knowledge and productivity will soar.
