Conclusion: I didn't quite understand the meaning of the question at the beginning. I gradually understood the question with the help of my friends. However, since I haven't written the code for too long and I don't know how to start it, I had to refer to how others wrote the code on the Internet, and then I remembered the knowledge I learned, I am familiar with it slowly. Although most of them are not written by myself, I have gained a lot.
