JAVA/Python/C++ 实现汉诺塔问题求解
可以使用以下代码来解决汉诺塔问题并输出求解步骤和总步数:
```python
def hanoi(n, source, target, auxiliary):
if n == 1:
print("Move disk 1 from {} to {}".format(source, target))
return 1
else:
step1 = hanoi(n-1, source, auxiliary, target)
print("Move disk {} from {} to {}".format(n, source, target))
step2 = hanoi(n-1, auxiliary, target, source)
return step1 + 1 + step2
n = int(input("Enter the number of disks: "))
total_steps = hanoi(n, 'A', 'C', 'B')
print("Total steps: ", total_steps)
```
在上面的代码中,我们定义了一个递归函数`hanoi`,它接收三个参数:n表示盘子的数量,source表示源柱子,target表示目标柱子,auxiliary表示辅助柱子。如果n等于1,则直接将盘子从源柱子移动到目标柱子,并返回1。否则,将n-1个盘子从源柱子移动到辅助柱子,然后将第n个盘子从源柱子移动到目标柱子,最后将n-1个盘子从辅助柱子移动到目标柱子。在移动每个盘子时,我们都会打印出移动的步骤。最后,在主程序中,我们调用`hanoi`函数来解决汉诺塔问题,并将总步数打印出来。
例如,如果我们输入数字3,则输出如下:
```
Enter the number of disks: 3
Move disk 1 from A to C
Move disk 2 from A to B
Move disk 1 from C to B
Move disk 3 from A to C
Move disk 1 from B to A
Move disk 2 from B to C
Move disk 1 from A to C
Total steps: 7
```
