I can understand why the Tower of Hanoi is a problem that requires a recursive algorithm, but I don't see how it specifically is a divide and conquer algorithm. Also, what's the concrete difference between the two? Is divide and conquer just a specific type of recursive algorithms? And what makes the TOH a divide and conquer algorithm specifally?

Answer #1

It is a divide and conquer algorithm because we divide the problem into smaller subproblems and then combine the results to generate the complete result.

Divide and conquer is a recursive strategy only.

In TOH problem we reduce the problem to n-1 disks and combine the results obtained from n-1 disks with the last disk to solve it for n disks.

So the reduction is divide step and combining is the conquer step in the algorithm
