Tower of Hanoi The Tower of Hanoi puzzle was invented by the French mathematician Edouard Lucas in 1883. © 2018 Koperasi AHM. Time complexity for the recursive solution: It is also easy to show that if you have 2 disks the minimum number of moves is 3. You are given 3 pegs with disks on one of them, and you must move all the disks from one peg to another, by following the given rules. There are 3 pegs, and all disks begin on one of the pegs. No larger disc can be placed on a smaller disc.

According to the legend of the Tower of Hanoi (originally the "Tower of Brahma" in a temple in the Indian city of Benares), the temple priests are to transfer a tower consisting of 64 fragile disks of gold from one part of the temple to another, one disk at a time. • Configurable number of disks. Tower of Hanoi is a mathematical puzzle which consists of three towers(or pegs) and n disks of different sizes, numbered from 1, the smallest disk, to n, the largest disk. You have 3 pegs (A, B, C) and a number of discs (usually 8) we want to move all the discs from the source peg (peg A) to a destination peg (peg B), while always making sure that a bigger disc never ends up on top of a smaller one. Move the top n-1 disks from source to auxiliary tower. Cambridge Online Learning Portal, i[r] = i[r] || function () { For example, you can arrange the squares in a circle and only allow disks to move clockwise. .wpb_animate_when_almost_visible { opacity: 1; }, Tower of Hanoi is a mathematical puzzle where we have three rods and n disks.
