Im very confused about this node. How does C's switch statement offer O(1) time? Im wracking my brain to see how this could be done without becoming hopelessly inefficient. Also your update is confusing too, the switch like code posted drops out of the loop once a condition has been met. I suppose strictly speaking a series of conditionals can be described as O(N), but this deosnt seem to match up with the spirit of your usage.
