  int row_size;
  scanf("%d", &row_size);
  int print_control_x = row_size;
  int print_control_y = row_size;
  for (out = 1; out <= row_size; out++)
  {
    for (in = 1; in <= row_size * 2; in++)
    {
      if (in == print_control_x || in == print_control_y)
      {
        printf("%d", out);
      }
      else
