这题要怎么做？代码尽量简单一点

#include<bits/stdc++.h>
#define maxn (1005)
using namespace std;

struct Student
{
  int Math,Chinese,English;
  int total;
  int num;
  bool operator < (const Student &other) const
  {
    if(total != other.total)
      return total > other.total;
    else
      return Chinese > other.Chinese;
  }
}student[maxn];

int main()
{
  int n;
  cin >> n;
  for(int i = 0;i < n;i++)
  {
    student[i].num = i+1;
    cin >> student[i].Chinese >> student[i].Math >> student[i].English;
    student[i].total = student[i].Chinese + student[i].Math + student[i].English;
  }
  sort( student , student + n );
  for(int i = 0;i < n;i++)
  {
    cout << student[i].num << ' ' << student[i].total << endl;
  }
  return 0;
}
