第一次：格式错误

 第二次：AC

两种方法：

#include <iostream>
#include <algorithm>
using namespace std;
bool forbid[10000];
int main() {
    int n, m, temp, k, snum = 0, fnum = 0;
    scanf("%d %d", &n, &m);
    for (int i = 0; i < m; i++) {
        scanf("%d", &temp);
        forbid[temp] = true;
    }
    for (int i = 0; i < n; i++) {
        char name[10];
        bool flag = false;
        scanf("%s %d", name, &k);
        for (int j = 0; j < k; j++) {
            scanf("%d", &temp);
            if (forbid[temp]) {
                if (!flag) {
                    printf("%s:", name);
                    flag = true;

        }
        if (flag) {
            printf("

            snum++;
        }
    }
    printf("%d %d
", snum, fnum);
    return 0;
