## How do you solve the Tower of Hanoi and disks?

Tower of Hanoi algorithm explained Looks simple, Right! Move Disk 1 from peg A to peg C. Then move disk 2 from peg A to peg B and, finally, move disk 1 from peg C to peg B. This solution takes 3 steps. You can easily move this stack from peg B to any other peg using these 3 steps.

**How many steps will it take to move 4 disks in Towers of Hanoi?**

For example if you have three disks, the minimum number of moves is 7. If you have four disks, the minimum number of moves is 15….The minimum number of moves for any number of disks.

Number of disks | Minimum number of moves |
---|---|

3 | (2 X3)+1 = 7 |

4 | (2X7)+1 = 15 |

5 | (2X15)+1=31 |

6 | (2X31)+1=63 |

## How is recursion used in Tower of Hanoi?

Tower of Hanoi consists of three pegs or towers with n disks placed one over the other. The objective of the puzzle is to move the stack to another peg following these simple rules. Only one disk can be moved at a time. No disk can be placed on top of the smaller disk. What is Recursion? When a function calls itself, it’s called Recursion.
