This sounds like homework. Go back to your teacher/tutor for
assistance, rather than asking us to do the work for you; or at very
least, word your question in such a way that we can help you to learn,
rather than just give you the answer.

Second problem: You're using Google Groups. This makes your posts
messy, especially when you quote someone else's text. Please either
fix your posts before sending them, or read and post by some other
means, such as the mailing list:
