## Which of the following is a rule of Tower of Hanoi problem?

Explanation: Objective of tower of hanoi problem is to move all disks to some other rod by following the following rules-1) Only one disk can be moved at a time. 2) Disk can only be moved if it is the uppermost disk of the stack. 3) No disk should be placed over a smaller disk. 2.

## How does recursion solve the Tower of Hanoi problem?

Using recursion often involves a key insight that makes everything simpler. In our Towers of Hanoi solution, we recurse on the largest disk to be moved. … 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.

## What is the goal and all the rules of Tower of Hanoi problem?

The goal is to move all the disks from the leftmost rod to the rightmost rod. To move N disks from one rod to another, 2^ −1 steps are required. So, to move 3 disks from starting the rod to the ending rod, a total of 7 steps are required.

## How many steps does it take to complete Tower of Hanoi if there are 5 disks?

Three is the minimal number of moves needed to move this tower. Maybe you also found in the games three-disks can be finished in seven moves, four-disks in 15 and five-disks in 31.

## What is the objective of Tower of Hanoi algorithm?

Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules: 1) Only one disk can be moved at a time.

## Which data structure can be used suitably to solve the Tower of Hanoi problem?

Stack approach is widely used to solve Tower of Hanoi.

## What is the formula for the Tower of Hanoi?

The original Tower of Hanoi puzzle, invented by the French mathematician Edouard Lucas in 1883, spans “base 2”. That is – the number of moves of disk number k is 2^(k-1), and the total number of moves required to solve the puzzle with N disks is 2^N – 1.

## Is Tower of Hanoi dynamic programming?
