No, that's not what we do here. When you signed up for your account, you were instructed to read a set of guidelines. In those guidelines, it is made clear that we do not do your homework for you, you must make an effort and show your attempts. TinyTim gave you a good hint, how far do you get when you try to apply his hint? (Post what you've got!)
