输入输出外挂

超快！！！

inline char nc() {
 static char buf [100000],*p1=buf,*p2=buf;
 return p1==p2&&(p2=(p1=buf)+fread(buf,1,100000,stdin),p1==p2)?EOF:*p1++;
}
inline int read() {
 static char c=nc(); int x=0,f=1;
 for(;c>'9'||c<'0';c=nc()) if(c=='-') f=-1;
 for(;c<='9'&&c>='0';c=nc()) x=(x<<3)+(x<<1)+c-48;
 return x*f;
}

正常版输入输出外挂

inline inline int read() {
    int x=0;
    char c=getchar();
    while(c<'0'||c>'9') c=getchar();
    while(c>='0'&&c<='9') x=x*10+c-'0', c=getchar();
    return x;
}
inline void out(int a){  
    if(a < 0) {putchar('-'); a = -a;}  
    if(a >= 10)out(a / 10);  
    putchar(a % 10 + '0');  
}
