```cpp
#include <iostream>
#include <algorithm>
using namespace std;
struct node
{
string name;
int year, mon, day;
int level;
void read()
{
cin >> name >> year >> mon >> day;
}
};
node a[105];
bool cmp(node a,node b){
if (a.year != b.year) return a.year < b.year;
else
{
if(a.mon != b.mon) return a.mon < b.mon;
else if(a.day == b.day && a.mon == b.mon) return a.level > b.level;
else if(a.day != b.day && a.mon == b.mon) return a.day < b.day;
}
}
int main()
{
int n;
cin >> n;
for (int i = 1; i <= n; i++)
{
a[i].read();
a[i].level = i;
}
sort(a + 1, a + n + 1, cmp);
for (int i = 1; i <= n; i++) cout << a[i].name << endl;
return 0;
}
