   Outer:
      for (i = 0; i < 5; i++)
      {
         Inner:
            for (j = 0; j < 5; j++)
            {  
               if (j == 2)
                  continue Inner;
               else
                  a[i,j] = j + 1;
            }
      }
      for (i = 0;i < 5; i++)
      {
         s = ""
         for (j = 0; j < 5; j++)
         {
            s += a[i,j];
         }
