## 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?

Tower of Hanoi (Dynamic Programming)
