# Frequent question: What is the time complexity of Tower of Hanoi problem Mcq?

Contents

Explanation: Time complexity of the problem can be found out by solving the recurrence relation: T(n)=2T(n-1)+c. Result of this relation is found to be equal to 2n.

## What is the time complexity of Tower of Hanoi problem?

Most of the recursive programs takes exponential time that is why it is very hard to write them iteratively . T(1) = 2k T(2) = 3k T(3) = 4k So the space complexity is O(n). Here time complexity is exponential but space complexity is linear .

## Which statement is correct in case of Tower of Hanoi Mcq?

The statement “Only one disk can be moved at a time” is correct in case of tower of hanoi.

## 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 will be the minimum time required to solve Tower of Hanoi?

The minimal number of moves required to solve a Tower of Hanoi puzzle is 2n − 1, where n is the number of disks.

## 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 is the time complexity of the solution Tower of Hanoi problem using recursion?

Explanation: Time complexity of the problem can be found out by solving the recurrence relation: T(n)=2T(n-1)+c. Result of this relation is found to be equal to 2n. It can be solved using substitution.

## What will be the minimum time required to solve Tower of Hanoi puzzle with 5 disks assuming one move takes 2 seconds?

Question 10 [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Minimum time required to solve tower of hanoi puzzle with 4 disks assuming one move takes 2 seconds, will be ….. Time for 15 moves = 15×2 = 30 seconds.

## What is recurrence relation of Tower of Hanoi problem?

Then the monks move the n th disk, taking 1 move. And finally they move the ( n -1)-disk tower again, this time on top of the n th disk, taking M ( n -1) moves. This gives us our recurrence relation, M ( n ) = 2 M ( n -1) + 1.

## Which of the following can be used to solve the Tower of Hanoi problem?

Stack approach is widely used to solve Tower of Hanoi.

## How does the Tower of Hanoi work?

Tower of Hanoi consists of three pegs or towers with n disks placed one over the other. The objective of the puzzle is to move the stack to another peg following these simple rules. Only one disk can be moved at a time. No disk can be placed on top of the smaller disk.

## What is the minimum number of moves required to solve the Tower of Hanoi problem with 4 dice?

If you have four disks, the minimum number of moves is 15.

## What is the Tower of Hanoi puzzle?

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.

## Which of the following problems can’t be solved using recursion?

2. Which of the following problems can’t be solved using recursion? Explanation: Problems without base case leads to infinite recursion call. In general, we will assume a base case to avoid infinite recursion call.
