【题目大意】给定N个同学的语数英成绩，按照题目的要求对学生求解排名。

【考纲知识点】排序算法

【解题思路】该题目做法多样，可用结构体/pair数组/truple等

总体流程:输入人数和对应的成绩,注意此时需要将人员的编号也存储下来,接下来按照比较优先级对人员进行排名：

优先级从高到低依次为:总分、语文数学总分、语文或数学最高分大的优先。

可以考虑用truple,将对应的优先级数值存储后，做一次sort降序即可。

【参考程序】

#include <iostream>
#include <algorithm>
#include <tuple>
using namespace std;
const int MAX_N = 10005;
tuple<int, int, int, int> students[MAX_N];
int main()
{
    ios::sync_with_stdio(false);
    int N;
    cin >> N;
    for (int i = 0; i < N; ++i)
    {
        int c, m, e;
        cin >> c >> m >> e;
        students[i] = make_tuple(c + m + e, c + m, max(c, m), i);
    }
    sort(students, students + N, greater<tuple<int, int, int, int>>());
    int rank[N];
    int curr_rank;
    tuple<int, int, int> last_student = make_tuple(-1, -1, -1);
    for (int i = 0; i < N; ++i)
    {
        if (make_tuple(get<0>(students[i]), get<1>(students[i]), get<2> (students[i])) != last_student)
        {
            last_student = make_tuple(get<0>(students[i]), get<1>(students[i]), get<2>(students[i]));
            curr_rank = i + 1;
        }
        rank[get<3>(students[i])] = curr_rank;
    }
    for (int i = 0; i < N; ++i)
    {
        cout << rank[i] << endl;
    }
    return 0;
}
