这骚操作简直让我望尘莫及~
（正儿八经写的以后更）

#include <iostream>
using namespace std;

int main(){
	string start = "1814/09/06", end = "2014/09/06";
	string minstr = "z", maxstr = "", minname, maxname, str, name; 
	int cnt = 0, n;
	cin >> n;
	for(int i = 0; i < n; i++){
		cin >> name >> str;
		if(str <= end && str >= start){
			cnt++;
			if(str > maxstr){
				maxstr = str;
				maxname = name;
			}
			if(str < minstr){
				minstr = str;
				minname = name;
			}
		}
	}
	if(cnt)
		cout << cnt << " " << minname << " " << maxname;
	else
		cout << "0";
	return 0;
}
