challenge problem: The Towers of Hanoi.

The Towers of Hanoi is a game played with three poles and a set of discs. The discs are graded in diameter, and fit onto the poles by means of a hole cut through the center of each disc. Initially all the discs are on the left-hand pole. The object of the game is to move all of the discs onto the center pole. The right-hand pole can be used as a "spare" pole, a temporary resting place for discs.
