```
#include<iostream>
#include<string>
#include<cstring>
#include<algorithm>
using namespace std;
struct btd{
string name;
int year,day,month;
int id;
};
bool cmp(btd a,btd b){
return (a.year!=b.year)?a.year<b.year:(a.month!=b.month)?a.month<b.month:(a.day!=b.day)?a.day<b.day:a.id>b.id;//用三元运算符会非常方便
}
