225讲汉诺塔、八皇后

汉诺塔

• 我不能理解

package main.daytwo;

public class HanoiTower {
    public static void main(String[] args) {
        Tower tower = new Tower();
        tower.move(3,'A','B','C');
    }
}
class Tower{
    public void move(int num, char a,char b,char c){
        if(num == 1){
            System.out.println(a + "->" + c);
        }else{
            //1.假设有2个盘。则需要把上面所有的盘看成一个盘。移动到b。借助c
            move(num - 1,a,c,b);
            System.out.println(a + "->" + b);
            //2.然后把num那个盘移动到c。
            System.out.println(a + "->" + c);
            //3.最后把num-1那一堆盘移动到c，借助b
            move(num-1,b,a,c);
            System.out.println(b + "->" + c);
        }
    }
}
