即使把程式簡化成下列,還是會逾時

#include <iostream>

using namespace std;
int main()
{
   
    int n,r,c,j,k,i,input;
   
   while (cin >> n)
      {
  
          for (i=1;i<=n;i++)
          {
               cin >> r;
               cin >> c;
           
            
            
            
             
              for (j=1;j<=r;j++)
              {
                  for (k=1;k<=c;k++)
                  {
                     cin>>input;
                    
                 
                  }}
             
       
              cout <<"1 1\n";
              cout <<"1\n";
             
             
             
              }
         
         
          }
         
         
   
   
   
   
   
   
   
   
    return 0;
    }
