Examples of Recursion

Problem : Write a function that takes the same arguments as TOH but instead of printing out the solution, returns the number of disc moves in solving the problem.

Problem : If the only change in the rules of the Towers of Hanoi problem were that you only had two poles instead of three, would the problem still be solvable?

Problem : If you have a problem that has a recurrence relation of T(n) = 2T(n/2) + 1, T(1) = 1 , what would be an appropriate big-O notation?

Problem : CHALLENGE: Write an iterative solution to the Towers of Hanoi problem.

Problem : In the iterative solution presented above, what is the purpose of the 1 << n? How does this relate to Towers of Hanoi?
