Which one of the following is recurrence relation for Tower of Hanoi?

First they move the ( n -1)-disk tower to the spare peg; this takes M ( n -1) moves. 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 is the correct recurrence for recursive Tower of Hanoi puzzle?

Explanation: As there are 2 recursive calls to n-1 disks and one constant time operation so the recurrence relation will be given by T(n) = 2T(n-1)+c. Explanation: Minimum number of moves can be calculated by solving the recurrence relation – T(n)=2T(n-1)+c.

Which recurrence relation describes the number of moves needed to solve the Tower of Hanoi puzzle with N disks?

With 3 disks, the puzzle can be solved in 7 moves. 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 the main aim of Tower of Hanoi recurrence problem?

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.

Why is the Tower of Hanoi recursive?

Writing a Towers of Hanoi program. 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 …

Which statement is correct in Tower of Hanoi?

Answer: option 2. only one disk can move at a time.

What is the objective of Tower of Hanoi?

The objective of the game is to move the entire stack to another rod, obeying the rules: Only one disk may be moved at a time. Each move consists of taking the upper disk from one of the rods and sliding it onto another rod, on top of the other disks that may already be present on that rod.

How many moves does it take to solve the Tower of Hanoi for 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.

Can you move all the disks to Tower 3?

Object of the game is to move all the disks over to Tower 3 (with your mouse). But you cannot place a larger disk onto a smaller disk.

What is the problem of Tower of Hanoi?

Initially, all the disks are placed on one rod, one over the other in ascending order of size similar to a cone-shaped tower. The objective of this problem is to move the stack of disks from the initial rod to another rod, following these rules: A disk cannot be placed on top of a smaller disk.

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

Stack approach is widely used to solve Tower of Hanoi.

How many disks are in the Tower of Hanoi?

Minimum moves with the Tower of Hanoi

In one version of the puzzle Brahmin priests are completing the puzzle with 64 golden disks. If you had 64 golden disks you would have to use a minimum of 264-1 moves. If each move took one second, it would take around 585 billion years to complete the puzzle!

Is Tower of Hanoi application of Stack?

The Tower of Hanoi is a mathematical game or puzzle. The objective of the puzzle is to move the entire stack to another rod, obeying the following rules: … 1) Only one disk must be moved at a time.

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

To write an algorithm for Tower of Hanoi, first we need to learn how to solve this problem with lesser amount of disks, say → 1 or 2. We mark three towers with name, source, destination and aux (only to help moving the disks). If we have only one disk, then it can easily be moved from source to destination peg.

What are the advantages and disadvantages of recursion?

Advantages/Disadvantages of Recursion #

  • To solve such problems which are naturally recursive such as tower of Hanoi.
  • Reduce unnecessary calling of function.
  • Extremely useful when applying the same solution.
  • Recursion reduce the length of code.
  • It is very useful in solving the data structure problem.
