Algorithm and flowchart for towers of hanoi. Three simple rules are followed. This presentation shows that a puzzle with 3 disks has taken 2 3 1 7 steps. The puzzle was invented by the french mathematician edouard lucas in 1883. The objective of this puzzle is to transfer the entire stack to another rod.
Towers of hanoi also known as lucas tower or tower of bramha s is a mathematical puzzle developed by a mathematician of french origin named édouard lucas. The target is to move both these disks to peg b. The solution of the puzzle is to build the tower on post c. Following is an animated representation of solving a tower of hanoi puzzle with three disks.
Tower of hanoi is a very famous game. The arbitrary towers of hanoi at start disks can be in any position provided that a bigger disk is never on top of the smaller one see fig. Disk 1 on top of disk 2 at peg a. Writing a towers of hanoi program.
Share in this tutorial we will learn to solve tower of hanoi using recursion. Tower of hanoi algorithm explained. In our towers of hanoi solution we recurse on the largest disk to be moved. Tower of hanoi problem explanation.
Only one disk can be moved at a time. It is believed that the solution and problem for. To write an algorithm for tower of hanoi first we need to learn how to solve this problem with lesser amount of disks say 1 or 2. Tower of hanoi is a mathematical puzzle with three rods and n numbers of discs.
The tower of hanoi algorithm in data structures is a very common interview question for beginners. Our function will also take three parameters indicating from which peg the tower should be. Move disk 1 from peg a to peg c. We mark three towers with name source destination and aux only to help moving disks.
The classical towers of hanoi an initial position of all disks is on post a. At the end disks should be in another arbitrary position. About tower of hanoi. Let s go through the steps through which you can solve the tower of hanoi first.
In this game there are 3 pegs and n number of disks placed one over the other in decreasing size. Before getting started let s talk about what the tower of hanoi problem is. Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack. Tower of hanoi algorithm and flowchart.
Let s try to solve a puzzle tower of hanoi using recursion. That is we will write a recursive function that takes as a parameter the disk that is the largest disk in the tower we want to move. Tower of hanoi puzzle with n disks can be solved in minimum 2 n 1 steps.
