示例1: Main
internal static void Main()
{
Deque<int> deque = new Deque<int>();
deque.PushFirst(3);
deque.PushFirst(5);
deque.PushFirst(7);
deque.PushLast(10);
deque.PushLast(13);
//The order of elements in Deque is: 7, 5, 3, 10, 13
//This will write on console first element without removing it from Deque -> 7
Console.WriteLine("Peek first element: {0}", deque.PeekFirst());
//This will write on console last element without removing it from Deque -> 13
Console.WriteLine("Peek last element: {0}", deque.PeekLast());
//This will write on console first element and remove it from Deque -> 7 again
Console.WriteLine("Pop first element: {0}", deque.PopFirst());
//This will write on console first element and remove it from Deque -> 5 again
Console.WriteLine("Pop first element: {0}", deque.PopFirst());
//This will write on console last element and remove it from Deque -> 13 again
Console.WriteLine("Pop last element: {0}", deque.PopLast());
//In the deque now you have only two elements -> 3 and 10
