And then put all other (n-1) disks onto it. Similarly if we will have n number of disk then our aim is to move bottom which is disk n from source to destination. His first win came in a state-level 3x3 puzzle cube competition. Lim is an avid speed solver and has won many speed solving competitions. And at last, we will move the disk from aux tower to the destination tower. When 08 March 2022 The fastest time to solve a 6 level Tower of Hanoi is 26.35 seconds, and was achieved by Lim Kai Yi (Malaysia) in Butterworth, Pulau Pinang, Malaysia, on 8 March 2022.Our Objective is to move all disks from initial tower to. And this disks are arranged on one over the other in ascending order of size. Initially, all the disks are placed on one rod. The Tower of Hanoi is a mathematical Puzzle that consists of three towers (pegs) and multiple disks. Then we will move the next disk (which is the bottom one in this case) to the destination tower. Tower Of Hanoi Algorithm, Explanation, Example and Program.First, we will move the top disk to aux tower.We have to move this disk from intial tower to destination tower using aux tower.įor an example lets take we have two disks and we want to move it from source to destination tower. In Tower Of Hanoi puzzle we have three towers and some disks.

Unit 2: Medium Access sub-layer (Data Link Layer) Abstract Addictive game of reflexes, speed and agility.Unit 1: Introduction to Computer Network.Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack. The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules: Only one disk can be moved at a time. Unit 1 – Introduction to Data Structure The Tower of Hanoi is a mathematical game or puzzle.I.e MoveDisks ( N - 1, aux_peg, source_peg, dest_peg ). Now that we have N - 1 disks on aux_peg, we could move them to dest_peg using source_peg ( as auxiliary peg ) Move the bottom-most disk N left on the source_peg to dest_peg.ĥ. I.e MoveDisks ( N - 1, source_peg, dest_peg, aux_peg ).Ĥ. First move the top ( N - 1 ) disks from source_peg to aux_peg using dest_peg ( which is used as an auxiliary peg ). Thus the rules of the puzzle are obeyed and we get the below recursive algorithm for solving the puzzle of Tower Of Hanoi.Īlgorithm : MoveDisks ( Integer disks, String source_peg, String using_peg, String dest_peg ) The bottom-most disk that is now left on the source peg is then moved to the desitnation peg. Idea : The idea behind recursion is to move the top ( N - 1 ) disks from source peg to auxiliary peg. If N = 3, we could have 2 3 - 1 = 7 moves.If N = 2, we could have 2 2 - 1 = 3 movesġ: Move the smaller disk at the top from peg A to peg B.Ģ: Move the bigger disk at the bottom from A to peg C.ģ: Move the smaller disk from peg B to peg C.If N = 1, we could just moved the disk from peg A to peg C without using the auxiliary peg.It can be mathematically proved that the minumum number of moves required to move N disks is 2 N - 1. A bigger disk cannot be placed on a peg containing a smaller disk.īelow is the example of solving the Tower Of Hanoi puzzle with 3 disks.At a time only one disk can be moved and placed on other peg.Objective : The puzzle would be solved if the entire stack of disks on peg A is moved to peg B using some simple rules.I.e the bottom most disk is biggest in diameter and as we go to the top the diameter of the stacked disks decreases. Beginning : The puzzle starts with all the N disks stacked on top of each other in decreasing order of diameter on peg A.Tower of Hanoi is a mathematical puzzle consisting of 3 pegs / towers and some disks of varying diameter.
