告别不懂为什么差个`if`会差16pts

@[Mayile1022](/user/782768) 它是在 cmp 里最后一行删了一个 else
by UperFicial @ 2023-08-17 20:24:38
就是第一个代码里写的cmp代码后面加了一个else，就是这样:
```c++
bool cmp(Stu x,Stu y)
{
if(x.year!=y.year) return x.year<y.year;
else if(x.month!=y.month) return x.month<y.month;
else if(x.day!=y.day)return x.day<y.day;
**else** return x.id>y.id;
}
```
但第二个每加
