开局一小板:
#include<bits/stdc++.h>
namespace kwx {
using namespace std;
#define LL long long
LL read() {
char c=getchar();
LL sum=0;
while(c<'0'||c>'9') {
c=getchar();
}
while(c>='0'&&c<='9') {
sum=(sum<<3)+(sum<<1)+c-'0',c=getchar();
}
return sum;
}
void write(LL x) {
if(x>9) {
write(x/10);
}
putchar(x%10+'0');
}
}
using namespace kwx;
int main() {
// freopen(".in","r",stdin);
// freopen(".out","w",stdout);
return 0;
}
