编辑点评：传统的汉诺塔游戏。游戏中有三根杆子，玩家需要将第一根杆子上的圆盘移动到第三根上，每次只能移动一个圆盘，大圆盘必须在小圆盘下面。

The Tower of Hanoi is a mathematical game or puzzle.
It consists of three rods, and a number of disks of different sizes which can slide onto any rod.
The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallest at the top, thus making a conical shape.

The objective of the puzzle is to move the entire stack to the red rod, obeying the following rules:

1. Only one disk may be moved at a time.
2. Each move consists of taking the upper disk from one of the rods and sliding it onto another rod, on top of the other disks that may already be present on that rod.

3. No disk may be placed on top of a smaller disk.
