computer science linked lists

A linked list is a sequence of nodes where each node contains two main components:

Data: The value or data the node is holding.

Next: A reference (or pointer) to the next node in the sequence.

 Types of Linked Lists

Singly Linked List: Each node points to the next node, and the last node points to null (or None in Python).

Structure:

Copy code

Head -> [Data | Next] -> [Data | Next] -> [Data | Next] -> Null

Doubly Linked List: Each node has two pointers, one pointing to the next node and one to the previous node.

Structure:

Copy code

Head <-> [Prev | Data | Next] <-> [Prev | Data | Next] <-> Null
