KY2 成绩排序 自测结果是对的，但是不知道为什么牛客网批改为错误

# include<iostream>

using namespace std;

    string name;
    int score;
};

bool Ascending(Student stu1,Student stu2){
        return stu1.score<stu2.score;
};
bool Descending(Student stu1,Student stu2){

    int n;
    int method;
    Student student[100];
    //cout<<"请输入学生人数";

    //cout<<"请输入排序方法0（降序）或者1（升序）";
    cin>>method;
    for(int i=0;i<n;i++){
        cin>>student[i].name>>student[i].score;

    }
