@[kun_yu](/user/1019780) sort改成stable_sort试试

@[kun_yu](/user/1019780) 再加一个O2

快读：
```cpp
int read(){
int ret=0, sgn=0, ch=getchar();
while(!isdigit(ch)) sgn|=(ch=='-'), ch=getchar();
while(isdigit(ch)) ret=ret*10+ch-'0', ch=getchar();
return sgn ? -ret : ret;
}
```

@[User904032](/user/904032) 用sort两个点TLE,用了stable_sort AC了，不懂怎么回事。
