水题，记录一下，处理输入挺有意义。

#include <iostream>
#include <map>
#include <string>
#include <algorithm>
using namespace std;
map<string, string> m1;
map<string, string> m2;
string s1, s2;
map<string, string>::iterator iter;
int main() {
	while(cin >> s1 && s1[0] != '@') {
		while(s1[s1.length() - 1] != ']') {
			s1 += ' ';
			cin >> s2;
			s1 += s2;
		}
		cin.ignore();
		getline(cin, s2);
		m1.insert(make_pair(s1, s2));
		s1.erase(s1.length() - 1, 1);
		s1.erase(0, 1);
		m2.insert(make_pair(s2, s1));
	}
	int n;
	cin >> n;
	cin.ignore();
	while(n--) {
		getline(cin, s1);
		if((iter = m1.find(s1)) != m1.end()) {
			cout << iter->second << endl;
			continue;
		}
		if((iter = m2.find(s1)) != m2.end()) {
			cout << iter->second << endl;
			continue;
		}
		cout << "what?" << endl;
	}
	return 0;
}
