@[暮天闻角](/space/show?uid=59636) 开O2还是过不了...尴尬QWQ

~~试试快读吧~~
```cpp
inline char get(){
static char buf[maxn],*p1=buf,*p2=buf;
return p1==p2&&(p2=(p1=buf)+fread(buf,1,maxn,stdin),p1==p2)?EOF:*p1++;
}
template<class A>inline void read(A &_){
_=0;char c=get();bool f=false;
while(c>'9' || c<'0'){if(c=='-')f=true;c=get();}
while(c>='0' && c<='9'){_=(_<<3)+(_<<1)+c-'0';c=get();}if(f)_=-_;
}
```

@[暮天闻角](/space/show?uid=59636) 一样,QWQ..可能要玄学剪枝

$register$ $int$，$inline$
以及一系列玄学
```cpp
#pragma GCC target("f16c")

~~话说这不是普通快读，此处有fread~~
```cpp
#define ll long long
inline char get(){
static char buf[30],*p1=buf,*p2=buf;
return p1==p2&&(p2=(p1=buf)+fread(buf,1,30,stdin),p1==p2)?EOF:*p1++;
}
inline ll read(){
register char c=get();register ll f=1,_=0;
while(c>'9' || c<'0')f=(c=='-')?-1:1,c=get();
while(c>='0' && c<='9')_=(_<<3)+(_<<1)+(c^48),c=get();return _*f;
}
```

等一下，，，这是道~~状压~~啊，，，~~您的爆搜理论上卡不过~~

~~刚刚玄学骗数据A了~~，不过rank2，似乎爆搜了
