{
    
    class Program
    {
        static void Main()
        {
            Queue Q = new Queue(5);

            Q.Enqueue(10);
            Q.Enqueue(20);
            Q.Enqueue(30);
            Q.Enqueue(40);

            Q.Clear();

            Console.WriteLine("All items deleted successfully");

        }
