1004. 成绩排名 (20)

求最大最小值，不需要排序

代码如下：

#include<iostream>
using namespace std;

int n,max_grade=-1,min_grade=150;
int grade_temp;
string name1,name2,num1,num2,name_temp,num_temp;
int main()
{
    int n;
    cin>>n;
    while(n--)
    {
        cin>>name_temp>>num_temp>>grade_temp;
        if(grade_temp>max_grade)
        {
            max_grade=grade_temp;
            name1=name_temp;
            num1=num_temp;
        }
        if(grade_temp<min_grade)
        {
            min_grade=grade_temp;
            name2=name_temp;
            num2=num_temp;
        }
    }
    cout<<name1<<" "<<num1<<endl;
    cout<<name2<<" "<<num2<<endl;
    return 0;
}
