Hacker News Reader

Are you the guy in that same class that points out how "obvious" everything is, in an attempt to prove how much smarter you are to the professor?

Yes. He's in the discussion about building a Hash function in C doing the exact same thing.

So everyone here is required to have a CS degree now?

Lots of self taught developers, and people with business or quantitative-but-not-coding backgrounds read Hacker News, I think.

I expect a higher level of content from HN, not basic material. I think other sites are more appropriate for this.

I wasn't taught this in my class, I was always dealing with very small lists so iterating did not make much of a difference.
