Tower of Hanoi in C: Step-by-Step Guide
The Tower of Hanoi problem is a classic recursive problem, and its solution steps are as follows:
- Create a recursive function to solve the Tower of Hanoi problem, with the prototype void hanoi(int n, char A, char B, char C), where n represents the number of disks, and A, B, C represent the three pegs.
- Within the function, the first step is to check if there is only one disk, in which case it should be moved directly to the target pole.
- If there are more than one plate, the task requires moving the top n-1 plates from A to B, then moving the bottom plate from A to C, and finally moving the n-1 plates from B to C.
- During the process of movement, problems can be divided into multiple sub-problems and solved by recursively calling the hanoi function.
- In the end, the entire Tower of Hanoi problem is solved by recursively moving all disks from A to C.
