**What Is Linear Data Structure? Give Examples**

A data structure is a way of organizing and storing data in a computer system. It provides a systematic way to access and manipulate the data efficiently. One of the fundamental types of data structures is the linear data structure.

__Linear Data Structure:__

A linear data structure is a type of data structure where elements are arranged sequentially or linearly. In this structure, each element has a unique predecessor and successor, except for the first and last elements. The order of elements remains fixed, and they can be accessed in a sequential manner.

Linear data structures are widely used in programming and form the building blocks for more complex data structures. They are simple, easy to understand, and efficient for performing basic operations like insertion, deletion, and searching.

__Examples of Linear Data Structures:__

## 1. Arrays:

An array is an example of a linear data structure where elements are stored at contiguous memory locations. It allows storing multiple values of the same type under a single variable name. Each element in an array can be accessed using its index position.

## 2. Linked Lists:

A linked list is another example of a linear data structure where elements are stored in nodes that contain both the value and a reference to the next node. The last node points to null, indicating the end of the list. Linked lists provide flexibility in terms of insertion and deletion but have slower access time compared to arrays.

## 3. Stacks:

A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It allows inserting elements at one end called the top and removing elements from the same end only. Stacks are commonly used in programming for handling function calls, expression evaluation, and undo operations.

## 4. Queues:

A queue is a linear data structure that follows the First-In-First-Out (FIFO) principle. It allows inserting elements at one end called the rear and removing elements from the other end called the front. Queues are used in various applications such as process scheduling, resource allocation, and breadth-first search algorithms.

## 5. Strings:

In programming, strings are considered as linear data structures where characters are stored sequentially in memory. They allow operations like concatenation, substring extraction, and searching within a text.

These are some of the common examples of linear data structures. Understanding their characteristics and operations is vital for efficient algorithm design and problem-solving in programming.
