This is a late comment, but I hope not out of place.
My daughter and I were working on a Jumble puzzle with a word we just couldn't crack. So, of course, I decided to throw the Perl wrench at it. As I thought about the algorithm, regular expressions just seemed like a natural choice.
I have to say this solution amazed me (I admit it, I'm not an experienced or professionally educatued programmer). I mean look at: 12 lines! And the solution -- how clever! Rather than looking for a match, it eliminates non-matches. I've learned something here.
OK, so I needed to solve a jumble, not find all possibilities. Two quick changes to one line, and I'm off:
next unless ( length $word == $#ARGV + 2 );
Great post, great solution. Thanks jonnybe
