Don't post late either. Posting math before bed is just as bad as posting code.

The above "correction" applies to how many elements wind up where they started. The algorithm commentary applies to how many times you make a useless swap. Those are different things. *sigh*

    Don't worry about it, we all make mistakes. Besides, you really did have it right the first time, and your correction is the mistake. It just goes to show that you are usually right the first time.
