Double Tower of Hanoi contains 2n disks of n different sizes, with two disks of each size. You must move all 2n disks from one of three locations to another, but you may move only one disk at a time, without putting a larger disk over a smaller one. Let T(n) be the number of moves necessary to move such a tower of 2n disks. Prove that T(n)=2n+1 −2foralln≥1.
