class MainClass
{
  public static void Main(string[] args)
  {
    for (int i = 0; i < 10; i++)
    {
      for (int j = 0; j < 10; j++)
      {
        Console.WriteLine(j);
      }
      for (int j = 0; j < 10; j++)
      {
        Console.WriteLine(j);
      }
      Console.WriteLine(i);
    }
  }
