# Which statement is correct in Tower of Hanoi?

Contents

The statement “Only one disk can be moved at a time” is correct in case of tower of hanoi. The Tower of Hanoi or Luca’s tower is a mathematical puzzle consisting of three rods and numerous disks. The player needs to stack the entire disks onto another rod abiding by the rules of the game.

## What is statement of Tower of Hanoi problem?

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: Only one disk can be moved at a time.

## What are the rules of Tower of Hanoi?

The rules of the puzzle are essentially the same: disks are transferred between pegs one at a time. At no time may a bigger disk be placed on top of a smaller one. The difference is that now for every size there are two disks: one black and one white. Also, there are now two towers of disks of alternating colors.

## What is the formula for 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.

## What is the objective of Tower of Hanoi?

The objective of the game is to move all the disks to another rod by moving only one disk at a time and a bigger disk cannot be placed on top of a smaller disk.

## What is Tower of Hanoi in DAA?

Advertisements. Tower of Hanoi, is a mathematical puzzle which consists of three towers (pegs) and more than one rings is as depicted − These rings are of different sizes and stacked upon in an ascending order, i.e. the smaller one sits over the larger one.

## What type of problem is the Tower of Hanoi?

Towers of Hanoi is a classic problem in computer science. Students usually encounter this problem as an example of recursion.

## Which of the following functions correctly represent the solution to Tower of Hanoi puzzle?

Which of the following functions correctly represent the solution to tower of hanoi puzzle? Explanation: The first recursive call moves n-1 disks from a to b using c. Then we move a disk from a to c. … Tower of hanoi problem can be solved iteratively.

## What is recursion explain recursion with Tower of Hanoi?

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 recursion explain Tower of Hanoi problem with algorithm?

Tower of Hanoi algorithm explained

Looks simple, Right! Move Disk 1 from peg A to peg C. Then move disk 2 from peg A to peg B and, finally, move disk 1 from peg C to peg B. … Now to solve the problem, recursively move disk 3 from peg A to peg B.

## Why is it called Towers of Hanoi?

The tower of Hanoi (also called the tower of Brahma or the Lucas tower) was invented by a French mathematician Édouard Lucas in the 19th century. It is associated with a legend of a Hindu temple where the puzzle was supposedly used to increase the mental discipline of young priests.

## What is the Tower of Hanoi psychology?

The Tower of Hanoi is a classical puzzle applied in the psychology of problem solving and skill learning. In the standard wooden version, it consists of three vertical pegs and a variable number of disks, usually three to five, with increasing diameter.

## What is the algorithm of the Tower of Hanoi for 5 disks?

The aim is to try and complete the transfer using the smallest number of moves possible. For example if you have three disks, the minimum number of moves is 7.

The minimum number of moves for any number of disks.

Number of disks Minimum number of moves
5 (2X15)+1=31
6 (2X31)+1=63
N-1 M

## What is the complexity of Tower of Hanoi?

The Tower of Hanoi problem with 3 pegs and n disks takes 2**n – 1 moves to solve, so if you want to enumerate the moves, you obviously can’t do better than O(2**n) since enumerating k things is O(k) .
