Linked List in Data Structures - (BCA / B.Tech)

Linked List in Data Structures:

A linked list is an important type of data structure used to store data elements in an ordered series. It is a dynamic data structure, where the method of storing data is very flexible. In a linked list, each element, called a node, is divided into two parts: the first part stores the data, and the second part stores the address (or reference) of the next node.

What is a Linked List?

A linked list is a linear data structure in which elements are placed in a sequential manner, one after another. Each node holds the address of the next node, connecting the entire list in a chain. It is different from other data structures like an Array, where elements are stored in a fixed order and the size is static. A linked list uses dynamic memory allocation, so its size can be easily increased or decreased.

Types of Linked Lists:

Singly Linked List: The simplest type, where each node holds the address of only the next node.
Doubly Linked List: Each node holds two addresses: one for the next node and one for the previous node.
Circular Linked List: The last node's next address points to the first node, making the list circular.
Circular Doubly Linked List: A circular version of a doubly linked list.

Structure of a Linked List: Each node in a linked list has two parts: Data and a Pointer to the next node.

Operations on a Linked List:

Insertion of a Node: Can be at the beginning, at the end, or in the middle.
Deletion of a Node: Can be from the beginning, from the end, or from the middle.
Searching in the List: The process of finding a specific node.
Printing the List: Displaying all the nodes in the list.

Advantages of Linked Lists: Dynamic sizing, efficient use of memory, and ease of insertion and deletion.
