Hi Eddie Z.,

You've asked 4 questions at the same time on essentially the same topic and requiring the same skills to solve. That's spamming; we're not here to solve your entire problem sets for you. Please cut your questions down to one (the hardest, perhaps?) and someone will undoubtedly help you!
