    If you supply the email of your teacher then we could save you wasting any effort on this by emailing him directly.

    Surely then you should just ask your lecturer (or a fellow student) to explain the question to you. It seems odd to expect us to do the question for you when you've done nothing towards solving it yourself. Of course if you genuinely haven't a clue how to go forwards then it might be worth questioning whether you're on the right course.

    Oddly the question contains a couple of small errors regards the names of coach c02 and member m123.

    either it's homework now, in which case you're busted, or you're studying on your own, and you ~clearly~ don't know enough yet, so go and read some more tutorials, there are literally hundreds of them on the web
