"// don't change this part
And wonder, "What the hell was I thinking?""
I have written in the past, to myself
/* Don't change this. You think it isn't right, but it is.
I've thought about it a lot recently, and it is right.
I know what you are thinking: you're thinking it should
be n+1 rather than n, but it shouldn't be, it should be n.
I mean it. If you do, you will get the wrong answer. */
