Problem Description约19世纪末，在欧州的商店中出售一种智力玩具，在一块铜板上有三根杆，最左边的杆上自上而下、由小到大顺序串着由64个圆盘构成的塔。目的是将最左边杆上的盘全部移到右边的杆上，条件是一次只能移动一个盘，且不允许大盘放在小盘的上面。现在我们改变游戏的玩法，不允许直接从最左(右)边移到最右(左)边(每次移动一定是移到中间杆或从中间移出)，也不允许大盘放到下盘的上面。Daisy已经做过原来的汉诺塔问题和汉诺塔II，但碰到这个问题时，她想了很久都不能解决，现在请你帮助她。现在有N个圆盘，她至少多少次移动才能把这些圆盘从最左边移到最右边？Input包含多组数据，每次输入一 阅读全文
