My books are dusty....

Pulled down my old CS books. I always knew there would be a reason to use them again...

It is amusing reading CS theory 15 years later and looking at how you write code now. I always hated O() crap, and I now remember why....

 2 * N * (N - 1) == 2 * N^2 - 2 * N == O(N^2)

My brain hurts...
