而且我的代码还WA了
```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
char a[5][5];
int i,j,ans=0;
for(i=1;i<=3;i++){
for(j=1;j<=3;j++){
cin>>a[i][j];
}
}
for(i=1;i<=3;i++){
for(j=1;j<=3;j++){
if(a[i][j]=='X' || a[i][j]=='O')ans++;
}
}
if(a[1][1]=='O' || a[1][3]=='O' || a[3][1]=='O' || a[3][3]=='O')cout<<"xiaoa will win."<<endl;
if(a[1][1]!='O' && a[1][3]!='O' && a[3][1]!='O' && a[3][3]!='O')cout<<"Dont know."<<endl;
cout<<ans<<endl;
return 0;
}
```

都说了xiaoa是愚蠢的
