E?
```cpp
#include<cstdio>
#include<cctype>
int read(){
int w=0,s=1;
char c=getchar();
while(!isdigit(c)){
s=(c=='-')?-1:1;
c=getchar();
}
while(isdigit(c)){
w=(w<<3)+(w<<1)+c-'0';
c=getchar();
}
return w*s;
}
```

@[Arvin2018](/space/show?uid=120766) $\rm fread$更快qwq
```cpp
#include<cstdio>
#include<cctype>
#define getc (l==r&&(r=(l=c)+fread(c,1,1<<21,stdin),l==r)?EOF:*l++)
char c[1<<21],*l=c,*r=c;
inline int read() {
int x=0; char ch=getc;
while (!isdigit(ch)) ch=getc;
while (isdigit(ch)) { x=x*10+(ch^48); ch=getc; }
return x;
}
