Can you explain how doubly linked lists work with a visualization?

Can you explain how doubly linked lists work with a visualization?

Sure! A doubly linked list is a data structure where each node contains a reference to both the next and the previous node.

Can you show me a simple visualization of a doubly linked list?

Absolutely! Imagine three nodes: Node A, Node B, and Node C. Node A points to Node B, Node B points to Node C, and Node B also points back to Node A.

What are the advantages of using a doubly linked list over a singly linked list?

Doubly linked lists allow traversal in both directions and make certain operations, like deletion, more efficient.

Can you give me an example of how to implement a doubly linked list in Python?

Sure! Here's a simple implementation:

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None
        self.prev = None

class DoublyLinkedList:
    def __init__(self):
        self.head = None
