No, that's what you would like, not what you need.

What you need is to make an effort to solve your own homework, then ask a specific question when you get stuck.

Wanting someone to spoon-feed you an answer while you go off partying or something just isn't going to happen.

If you don't make an effort on this one, the next homework is going to look even more impossible to you. If you can't deal with this, just drop the course now.

Can someone show this moron why we don't give away code?
Now, that's a question.

Is not a question.
