汉诺塔java代码递推思想，变化对象

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Demo2056 {

public static void main(String[] args) {

Scanner scanner=new Scanner(System.in);

while (scanner.hasNext()) {

      int n=scanner.nextInt();

      Hannuota(n,"1","3","2");

}

}

//string from代表的是原木柱

//string to代表的是目标木柱

//string help代表的是辅助木柱

public static void Hannuota(int n,String from,String to,String help) {

if (n==1) {

System.out.println("Move "+n+" from "+from+" to "+to);

}

//将其前n-1个圆筒放在辅助木柱上，将最后一个盘子放在目标木柱，再将辅助木柱的前n-1个盘子移动到目标木柱上

else {

Hannuota(n-1,from,help,to);//将其中的n-1个盘子移动到辅助盘子中

System.out.println("Move "+n+" from "+from+" to "+to);//将第n个盘子移动到c盘子中

Hannuota(n-1,help, to, from);//将前n-1个盘子放入到c盘子中

}

}

}
