Cs 222 02extra Credit Assignment 02 Chapter 03up To 10 Pointsduewedn Implement a queue using linked lists in Python, including all methods present in the list-based queue implementation. The linked list should be constructed based on the discussed structure, and the assignment requires deciding which end is the front and which is the back. Develop a test program that demonstrates the functionality of your linked list-based queue, covering all methods with clear, understandable output. At the beginning of the program, include comments with your name, class and section, assignment details, due date, date turned in, and a brief description of the program's purpose.

The implementation of queue data structures plays a vital role in computer science, particularly in managing data in a first-in, first-out (FIFO) manner. While Python's built-in list module provides a straightforward approach to implementing queues, leveraging linked list structures offers an efficient alternative, especially for dynamic memory management. This paper details the development of a queue based on linked list principles, encompassing all primary methods, and presents a comprehensive test program to validate its functionality. Introduction The queue is a fundamental abstract data type used extensively for organizing data where the order of processing is critical. It reflects real-world scenarios such as lineups or print queues. In Python, one can implement queues either by utilizing the list module or via custom data structures like linked lists. The linked list approach offers advantages such as efficient insertions and deletions without shifting elements. This assignment focuses on creating a queue by implementing a singly linked list, with a flexible choice of setting the front and back ends. Design and Implementation The linked list-based queue comprises nodes, each containing data and a reference to the next node. The queue maintains references to the front and rear nodes, enabling constant-time enqueue and dequeue operations. The methods implemented include enqueue, dequeue, peek, is_empty, size, and display. Following the class design, the program initializes a queue, performs various operations, and outputs the results with descriptive messages for clarity. Method Details Enqueue (add): Adds an element at the rear of the queue. If the queue is empty, both front and rear are set to the new node. Dequeue (remove): Removes and returns the element at the front. If the queue becomes empty, rear is also set to None. Peek: Returns the element at the front without removing it. is_empty: Checks whether the queue is empty. Size: Returns the number of eleme
