本地测样例正常，但是评测4个RE一个WA

#include<iostream>
using namespace std;
int main() {
    int n, c[7], t[7], x[7] = {0}, a = 0;
    cin >> n;
    for (int i = 0; i < 7; i++) cin >> c[i];
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < 7; j++) cin >> t[i];
        for (int k = 0; k < n; k++) {
            for (int l = 0; l < 7; l++) {
                if (c[k] == t[l]) a++;
            }
        }
        x[a] += 1;
    }
    for (int i = 6; i >= 0; i--) cout << x[i] << ' ';
    return 0;
}
