My AC Code，结构体排序，应该能看懂吧

从你的代码来看的话问题确实不大，但是从测评记录上来看的话大概是排序的问题，这里我觉得是你的cmp的问题，可以把if分开写，因为这是一个函数return之后就没了，所以if一个return一个

首先是逻辑问题，应该是年份，月份小的的年龄大，也就是把结构体判断else中大于改为小于；其次是第十行应该是a.ri==b.ri

@[Real_Luka_Modric](/user/671139) AC代码:
```cpp

if (x.d != y.d) return x.d < y.d;
return x.pm > y.pm;
}

sort(a + 1, a + n + 1, cmp);
for (int i = 1; i <= n; i++)
