2. Implement towers of Hanoi and calculate the number of recursive calls for n=3. 1 Algorithm TowersOfHanoi(n,x, y, z) 2 // Move the top n disks from tower x to tower y. 3 { if (n > 1) then { 6 TowersOfHanoi(n - 1, 1, 2,y); 7 write ("move top disk from tower", t, 8 "to top of tower", y); 9 TowersOfHanoi(n - 1, z, y,x); 10 } 11 } Towers of Hanoi
