RE: Group and sort by group element occurrences

As a long time reader, you should know that you will get a reply asking
you to post your code! We can't tell you what you're doing wrong unless
you show us what you're doing.

(Someone might post you a solution, but not me. That's not just because
I'm too busy to write code for people, it's because I don't think it's a
good way of learning. Your error might be a simple typo, or it might
reflect a deep misunderstanding of the concepts, and before I can give
you useful advice, I need to know which is the case.)
