It sounds like it is indeed what he wants, however, this is likely a homework assignment and the idea is that your program COULD produce the answer for that if he wanted, not that he will actually be using the result.

I'd handle it with recursion, myself.  It sounds like a cool idea for a game of Code Golf on Stack Exchange.
