Also, I think a lot of people miss the point of implementing things like linked lists, hash tables, etc...

Yes, they've been done before. Yes, you could find a code somewhere and copy/paste. But that's not the point. The point isn't to implement those specific things with known solutions, but to see if you can problem solve just in general, to see if you could possibly solve problems which don't have known solutions, which are interesting.

If you can't implement the simple stuff then how can you be expected to implement anything more complex?
