您好会员13246826，



因为这是你的功课，你需要考虑一下。我看到了问题，但我不应该告诉你解决方案。



但是，我可以给你一个提示 - 阅读有关按值传递参数，并传递参数的方法参考。我希望你能找到答案并根据需要更正代码。

Hi Member 13246826,

As this is your homework, you need to think about it. I see the problem but I should not be telling you the solution.

However, I can give you a hint - read about passing parameter by value, and passing parameter by reference. I hope you will find the answer and correct the code as needed.
