So you're just expecting us to do your homework for you? I'm pretty sure that isn't going to happen. We're here to help, and most of us love to help, but we're not your personal homework service.

I am not asking you to do all of these. I am just asking for help and guidance in solving these programs because I am thinking that people here might help me through sharing easier-to-understand codes than my professor provides.
