As was observed earlier, I think that better examples would have resulted in better code. I was mostly interested in finding a rubyish way to make it happen with great simplicity. If there is something slightly different needed, perhaps a tweak or two to the arrays before applying the differences could handle it. Anyway, this is my first attempt at writing code to solve a question in here. I am happy that I was able to come up with something that worked and post it. :) yay ruby! -- Posted via http://www.ruby-forum.com/.
