c) Given a Python Queue class implemented with the abstract data type (ADT) below, write anew method popqueue(), which will “pop" (remove and return) the last-in element fromthe rear end of the queue.| Operation (Queue) DescriptionsizeQ():int| GIVEN: Get (and return) the size of the queue (total number of elements)enqueue (elt):dequeue (): eltpopqueue(): elt Remove (and return) the last-in element from rear end of QueueGIVEN: Insert elt into QueueGIVEN: Remove (and return) element from QueueFinish this new Python popqueue () method, by completing the method body below:def popqueue ( self ): # remove and return rear elt# body of the method. TO BE COMPLETED by studento No other extra variable could be added including Python's list, except int andrange with function range().o No more than 4 lines of typical python code (without semicolon symbol ;) allowed inthe method body.* Hint: you may finish this task using its own given methods of the Queue class, and a forloop with function range().

b. Write out the order of elements that are contained in a queue after the following operations are performed. myQueue.enqueue(new Integer(16)); myQueue.enqueue(new Integer(12)); Integer num1 = myQueue.dequeue(); myQueue.enqueue(new Integer(6)); myQueue.enqueue(new Integer(8)); myQueue.enqueue(new Integer(30)); myQueue.enqueue(new Integer(24)); myQueue.enqueue(new Integer(18)); myQueue.dequeue(); myQueue.dequeue(); myQueue.dequeue(); myQueue.enqueue(new Integer(38); Show how step by step process of arriving at your answer.
Change the __str__ method of the Queue class (provided below) so that it prints each object in the queue along with its order in the queue (see sample output below). class Queue(): def __init__(self): self.queue = [] # implement with Python lists! # start of physical Python list == front of a queue # end of physical Python list == back of a queue def enqueue(self, new_obj): self.queue.append(new_obj); def dequeue(self): return self.queue.pop(0) def peek(self): return self.queue[0] def bad_luck(self): return self.queue[-1] def __str__(self): return str(self.queue) # let's try a more fun waySample output: >>> my_queue = Queue()>>> everyone = ["ESC", "ABC", "YOLO", "HTC"]>>> for initials in everyone:>>> my_queue.enqueue(initials)>>> print(my_queue)Output: 1: ESC2: ABC3: YOLO4: HTC
You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects…
