Yes I agree that there are algorithms that I would have never known about without hitting the books, I came across this recently. I was trying to solve one of ITA software hiring puzzles(Just for fun somebody mentioned it in SO) the "instant search" puzzle, I could never find a solution to the problem I spent days playing with it until I decided to give up, a few months later I found out about "Suffix trees" from wikipedia and found an implementation in Java, I'm still trying to understand about how it works but I used it in the ITA puzzle and the thing actually works and its freaking FAST!.
