Here is my code. Can anyone help me, please.
#include <iostream>
#include <sstream>
#include <string>
#include <vector>
#include <deque>
#include <queue>
#include <set>
#include <map>
#include <algorithm>
#include <functional>
#include <utility>
#include <cmath>
#include <cstdlib>
#include <ctime>
#include <cstdio>
#include <cstring>
//#include <conio.h>

using namespace std;

#define oo 1000000000
#define fi first
#define se second
#define sqr(a) ((a)*(a))
#define FR(i,n) for (int i = 0; i < (n); i++)
#define DN(i,a) for(int i = (a)-1; i >= 0; i--)
#define FOR(i,a,b) for (int i = (a); i <= (b); i++)
#define DOWN(i,a,b) for(int i = (a); i >= (b); i--)
#define FORV(i,a) for(typeof(a.begin()) i = a.begin(); i != a.end(); i++)

typedef pair<int, int> PII;
typedef vector<int> VI;

map<string, int> gavemin, gavemax;

int main () {
    int n, resmin = 0, resmax = 0;
    cin >> n;
    for (int i = 0; i < n; i++) {
        string name, state;
        cin >> name >> state;
        if (state != "AC") {
            int x;
            cin >> x;
            if (x >= 6 && gavemax[name] == 0) {
                gavemax[name] = 1;
                resmax++;
            }
            if (x == 7 && gavemin[name] == 0) {
                gavemin[name] = 1;
                resmin++;
            }
        } else if (gavemax[name] == 0) {
                resmax++;
                gavemax[name] = 1;
        }
    }
    cout << resmin << ' ' << resmax << endl;
    return 0;
}
Thanks.
