I am new to Ruby but I am wondering why it is that no one is using the uniq call that gets rid of duplicates in an array. Couldn't you join the two arrays, then call MyJoinedArray.uniq!, then take the resulting set and format it as you please? I know that you are doing more than just that. I was mostly wondering why you would not use the built in call. -- Posted via http://www.ruby-forum.com/.
