What is a Linked List?

A linked list is a linear data structure where elements are stored in nodes. Each node contains data and a reference (or link) to the next node in the sequence.

Types of Linked Lists

• Singly Linked List: Each node points to the next node.

• Doubly Linked List: Each node points to both the next and the previous node.

• Circular Linked List: The last node points back to the first node.

Advantages of Linked Lists

• Dynamic size: Can grow or shrink as needed.

• Efficient insertions and deletions: Easy to add or remove elements without shifting other elements.

Basic Operations

• Traversal: Visiting each node in the list.

• Insertion: Adding a node to the list.

• Deletion: Removing a node from the list.

Activity:

• Implement a linked list in a programming language of your choice. Perform operations like traversal, insertion, and deletion of nodes.
