As I've been trying to help people since I first became developed enough to register for gunz forums'. I can, from expereince say you should go google it yourself and put in some effort instead of wasting some nice guys' time whos gonna make like a wall of text that you wont use anyways because you're too lazy. those are like basic problem solving and logic questions, instead of relying on other people to teach, and think for you, think for yourself.
