                    Time Limit: 1 Second      Memory Limit: 32768 KB

I guess most of us are so called 80ers, which means that we were born in the 1980’s. This group of people shared a lot of common memories. For example, the Saint Seiya, the YoYo ball, the Super Mario, and so on. Do you still remember these?

Input

There will be ONLY ONE test case.

The test case begins with a positive integer N, (N < 100).
Then there will be N lines each containing a single word describing a keyword of the typical 80ers’ memories. Each word consists of letters, [a-zA-Z], numbers, [0-9], and the underline, ‘_’. The length of each word would be no more than 20.
Then one line follows with a positive integer K, (K < 100).
The last part of the test case will be K lines. The i-th line contains the keywords given by the i-th person and starts with a positive integer Ni. Then there will be Ni words separated by white spaces. Each of these words has no more than 20 characters.
All the words are case sensitive.

Output

For each of these K people, you are asked to count the number of typical 80ers’ keywords on his/her list and output it in a single line.

Super_Mario

题目思路：水题，利用map

以下是代码：

#include <vector>
#include <map>
#include <set>
#include <algorithm>
#include <iostream>
#include <cstdio>
#include <cmath>
#include <cstdlib>
#include <string>
#include <cstring>
using namespace std;
map <string,int> mp;
int main(){
    int n;
    cin >> n;
    for (int i = 0; i < n; i++)
    {
        string s;
        cin >> s;
        mp[s] = 1;
    }
    int k;
    cin >> k;
    while(k--)
    {
        int num;
        cin >> num;
        int cnt = 0;
        for (int i = 0; i < num; i++)
        {
            string ret;
            cin >> ret;
            if (mp[ret] == 1) cnt++;
        }
        cout << cnt << endl;
    }
    return 0;
}
