Given is a tower of n disks, initially stacked in decreasing size on one of three pegs. We want to transfer the entire tower to one of the other pegs, moving only one disk at a time and never moving a larger disk onto a smaller one. How many moves are necessary and sufficient to perform this task? Hints: Let a, be the moves which are necessary to perform this task for n disks. Determine a1, a2, and a3 (by hand) •Suppose that you knew what is the most efficient way to transfer a tower of n disks following the required rule (we do not care how you were able to do it, just assume you were able to do so). What is then the most efficient way to transfer a tower of n + 1 disks from one peg to another? Using the recurrence relation between an+1 and an found after the previous hint, determine the closed-form expression for an
