【模板】 快读快写模板
快读:
inline int read(){
char c = getchar();int x = 0,s = 1;
while(c < '0' || c > '9') {if(c == '-') s = -1;c = getchar();}
while(c >= '0' && c <= '9') {x = x*10 + c -'0';c = getchar();}
return x*s;
}
快写:
void write(int x){
if(x<0) putchar('-'),x=-x;
if(x>9) write(x/10);
putchar(x%10+'0');
return;
}
都挺简单的所以没加注释qwq
