P3367能不能卡到44ms呢 我的代码

#include<stdio.h>
#include<ctype.h>
#define f(x) while(x^fa[x])x=fa[x]=fa[fa[x]]

#define p(x) (*(outptr++)=(x))
inline int read(){register int x=0;register char ch=gch();for(;!isdigit(ch);ch=
gch());for(;isdigit(ch);ch=gch())x=(x<<1)+(x<<3)+(ch^48);return x;}
int m,op,x,y;

fwrite(outbuf+1,outptr-outbuf,1,stdout);return 0;}
