Exercise 5 The towers of Hanoi problem consists of three pegs A, B, and C, and n squares of varying sizes. Initially the squares are stacked on peg A in order of decreasing size, the largest square on the bottom. The problem is to move the squares from peg A to peg B one at a time in such a way that no square is ever placed on a smaller square. Peg C may be used for temporary storage of squares. A. Write a recursive algorithm to solve this problem. Answer here:

Exercise 5
The towers of Hanoi problem consists of three pegs A, B, and C, and n squares of varying sizes.
Initially the squares are stacked on peg A in order of decreasing size, the largest square on the
bottom. The problem is to move the squares from peg A to peg B one at a time in such a way that
no square is ever placed on a smaller square. Peg C may be used for temporary storage of
squares.
A. Write a recursive algorithm to solve this problem.
