输入输出格式一定要与样例一样，连一个空格，逗号都不能少，否者就会报错。

C++代码如下：

#include <iostream>
#include <vector>
#include <string>
#include <map>

using namespace std;

int main()
{
    int cCount = 0;
    int vCount = 0;

    while (cin >> cCount)
    {
        map<string, int> map;
        vector<string> vec(cCount,"");
        string str = "";

        for (int i = 0; i<cCount && cin >> str; i++)
        {
            map[str] = 0;
            vec[i] = str;
        }

        cin >> vCount;

        for (int i = 0; i<vCount && cin >> str; i++)
            if (map.find(str) != map.end())
                map[str]++;

        int count = 0;
        for (auto it = vec.begin(); it != vec.end(); it++)
        {
            cout << *it << " : " << map[*it] << endl;
            count += map[*it];
        }

        cout << "Invalid : " << vCount - count << endl;
    }

    return 0;
}
