Here the number of disks are 2, so this algorithm took (2 pow 2) – 1 = 4 – 1 = 3 steps. '.format(disks, source, target))ĭisks = int(input('Enter number of disks: ')) Python Code: def tof(disks, source, middle, target):

Then, move the nth disk from source tower to destination tower.Move n-1 disks from source tower to middle tower.The algorithm for this problem as follows:.
MOVE METHOD HANOI TOWERS HOW TO
How to solve the Tower of Hanoi Problem Algorithm for Tower of HanoiĬonsider the three towers as the source, middle, destination. See this animation below to understand more clearly: For example, if there are 3 disks, then the time to complete this algorithm takes (2 pow 3) -1 = 8 – 1 = 7 steps. Tower of Hanoi algorithm can be solved in (2 pow n) – 1 steps. A disk can be moved from one tower to another tower only if there is no disk on the top of the disk to be moved.That means no disk should be placed on top of a disk.

That means that if disk 1 (the smallest) moves clockwise, then 1, 3, 5, 7. RULE 2: Alternate disks move in opposite directions. RULE 1: A single disk will move in only one direction - clockwise or counter-clockwise. The objective of the puzzle is to move all the disks from. The puzzle starts with the disk in a neat stack in ascending order of size in one pole, the smallest at the top thus making a conical shape. It consists of three poles and a number of disks of different sizes which can slide onto any poles. Now, each time you move a disk, it's going to move either clockwise or counter-clockwise. The Tower of Hanoi is a mathematical puzzle. Here's a different way to understand how the disks move in a Towers of Hanoi solution, that makes it easy to write an iterative solution:Īrrange the pegs in a triangle like this: A C Put the algorithm in your hands We cant move the largest disk to peg C until its the only disk on peg A, and peg C is empty In order for that to be true. How long would it take to move 64 disks N disks To create an algorithm to solve this problem. The iterative solution is often more efficient, but requires a deeper insight. Assume one disk can be moved in 1 second. When a problem has both recursive and iterative solutions, the recursive solution is usually easier to formulate and understand.
