About โ€œTower of Hanoiโ€

An old math puzzle: all the disks are on the first peg and you must move them to the last one. Only the top disk can be moved, and a disk can never go on a smaller one.

Three disks take seven moves, and five need thirty-one. When a child works out the method alone, they have understood the idea of a recursive solution without ever hearing the word.
