using System.Threading.Tasks;
namespace TestApplication
{
class Program
{
    static void Main(string[] args)
    {
        Queue qt = new Queue();
        qt.Enqueue(1);
        qt.Enqueue(2);
        qt.Enqueue(3);
        foreach (Object obj in qt)
        {
            Console.WriteLine(obj);
        }
        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("The number of elements in the Queue " + qt.Count);
        Console.WriteLine("Does the Queue contain " + qt.Contains(3));
        Console.ReadKey();
    }
