The objective of towers of hanoi is to move all blocks from the leftmost peg to the rightmost peg. Only a single disc is allowed to be transferred at a time. But the world has already ended many times now,and its probably become quite boring to even talk about it. I am starting with a vertical slice of the gameplay, so for now, you can only mine minerals from the asteroids, build solar power stations, upgrade your structures, and defend yourself from neverending waves of enemy ships. I want to print the contents of each stack at each step, but i fail, although the algorithm works fine. If there is more than one disk, the algorithm moves n 1 disks to tower b, then moves the largest disk to tower c, and then moves the n 1 disks from tower b to tower c.
