```
#include<bits/stdc++.h>
using namespace std;
int main(){
int a=0,i,j;
char b[5][5];
for(i=1;i<=3;i++)
for(j=1;j<=3;j++)
{
cin>>b[i][j];
if(b[i][j]!='-')
a++;//有几个棋子
}
if((b[1][2]=='X'&&b[3][2]!='O')||(b[3][2]=='X'&&b[1][2]!='O')||
(b[2][1]=='X'&&b[2][3]!='O')||(b[2][3]=='X'&&b[2][1]!='O'))
cout<<"xiaoa will win.";//极限条件
else cout<<"Dont know.";
cout<<'\n'<<a;//输出棋子
return 0;
}```
这是我用小号写的题解，你看看吧
