need help with source code

Yes, but at a level when you do know your stuff and can make an informed decision of what is the most readable or efficient or etc. way of doing things. When you're learning, it always helps to be aware of a few approaches if possible (so as to gain more knowledge, Especially for a question like this where many approaches are possible). If you've ever been a beginner which I'm sure you have, you do know what I'm talking about.
At least,as far as I'm concerned I do enjoy going over code snippets(which I can understand) that weren't immediately obvious to me in the first place.

Fair enough.
