I've gone through all the questions on that website at least twice many of them three times with a whiteboard, I'll try putting it on the wall. Like I said though I knew that I had done this question before and knew how to do it. Just like I knew that (x > 0 || x < 0) is the same thing as (x != 0). I think its the actual being in front of a stranger part that I need to practice most.
