**What Is Linear Data Structure and Non Linear Data Structure?**

Data structures are an essential part of computer science and programming. They provide a way to organize and store data efficiently, allowing for easy access and manipulation.

There are various types of data structures, each with its own characteristics and use cases. Two fundamental categories of data structures are linear data structures and non-linear data structures.

## Linear Data Structures

__Linear data structures__ are those in which the elements are organized in a sequential manner, where each element is connected to its previous and next element (except for the first and last elements). These structures follow a linear order, allowing for easy traversal through the elements from one end to another.

### Examples of Linear Data Structures:

**Arrays:**Arrays are one of the most basic linear data structures. They store elements in contiguous memory locations, making it easy to access any element using its index.**Linked Lists:**Linked lists consist of nodes where each node contains a value and a reference to the next node.Unlike arrays, linked lists do not require contiguous memory allocation.

**Stacks:**Stacks follow the Last-In-First-Out (LIFO) principle. Elements can only be inserted or removed from the top of the stack.**Queues:**Queues follow the First-In-First-Out (FIFO) principle. Elements can only be inserted at one end (rear) and removed from the other end (front).

## Non-Linear Data Structures

__Non-linear data structures__, on the other hand, do not follow a sequential order. The elements in these structures are interconnected in a more complex manner, forming relationships between various elements.

### Examples of Non-Linear Data Structures:

**Trees:**Trees are hierarchical data structures with a root node and child nodes. Each child node can have its own child nodes, forming a tree-like structure.**Graphs:**Graphs consist of vertices and edges, representing connections between various entities. They are widely used to model complex relationships and networks.

In conclusion, linear data structures and non-linear data structures play crucial roles in organizing and manipulating data efficiently. Linear data structures provide a simple sequential order for elements, while non-linear data structures allow for more complex relationships between elements. Understanding the characteristics and use cases of different types of data structures is essential for efficient programming and problem-solving.
