程式碼如下:
#include<bits/stdc++.h>
using namespace std;
int main()
{
 ios::sync_with_stdio(0);
 cin.tie(0); 
 int t;
 cin>>t;
 for(int r=1;r<=t;r++)
 {
 int t2;
 //char c;
 cin.ignore(10,' ');
 cin.ignore(10,' ');
 cin>>t2;
 //cout<<t2<<"t";
 //cout<<t2<<"\n";
 long long int n[t2][t2];
 for(int i=0;i<t2;i++)
 {
 for(int j=0;j<t2;j++) cin>>n[i][j];
 }
 bool f=1;
 for(int i=0;i<t2;i++)
 {
 for(int j=0;j<t2;j++)
 {
 if(n[i][j]!=n[t2-1-i][t2-1-j]||n[i][j]<0) {f=0;break;
 }
 //cout<<n[i][j]<<" "<<n[t2-1-i][t2-j-1]<<"\n";
 }
 }
 cout<<"Test #"<<r<<": ";
 if(f) cout<<"Symmetric.\n";
 else cout<<"Non-symmetric.\n";
 }
}
