Insertion of a Node in a Linked List Data
Structure
In this article, we will explore the concept of inserting a node in a linked
list data structure. Linked lists are an important data structure in
computer science and are widely used to store and manipulate data
efficiently. We will discuss the process of inserting a new node into a
linked list and explore different scenarios and techniques involved in
this operation.

, 1. Introduction to Linked Lists
Linked lists are a dynamic data structure consisting of nodes connected
together in a linear sequence. Each node contains data and a reference
(or pointer) to the next node in the list. This arrangement allows for
efficient insertion and deletion of elements in the list.
2. Overview of Node Insertion
Node insertion involves adding a new node to the existing linked list.
The new node is inserted at a specific position, such as the beginning,
end, or somewhere in between. The process of node insertion requires
updating the pointers of the neighboring nodes to maintain the
connectivity of the list.
3. Inserting a Node at the Beginning of a Linked List
To insert a node at the beginning of a linked list, we follow these
steps:
Create a new node with the desired data.
Set the next pointer of the new node to the current head of the list.
Update the head pointer to point to the new node.
By performing these steps, the new node becomes the first element of
the linked list, and its next pointer points to the previous first node.
