The Tower of Hanoi is a classic mathematical puzzle consisting of three pillars and a number of discs of different sizes. Initially all the disks are stacked on a pillar in order from largest to smallest. The goal is to move all the disks from the starting pillar to another while keeping the size order unchanged during the move. The rules of the game are as follows: 1. Only one disc can be moved at a time. 2. Each time you move, you can only place the smaller disk on top of the larger disk. 3. Throughout the game, the discs remain in the same stacking order between the three pillars. According to the Tower of Hanoi rule, the minimum number of steps to solve the Tower of Hanoi problem is 2 to the nth power minus 1, where n is the number of disks. The Tower of Hanoi problem is a classic recursion problem that plays an important role in the fields of computer science and mathematics and is often used in teaching and algorithm analysis. It demonstrates the power of recursive algorithms and a way of thinking. Students can understand the title of the Tower of Hanoi problem by reading the text on the screen, and think about how to solve the Tower of Hanoi problem themselves.
