**What Is a Pure Data Structure?**

A data structure is a way of organizing and storing data in a computer’s memory. It provides a systematic way to access and manipulate data efficiently. One type of data structure is known as a pure data structure.

## Definition

A pure data structure is a data structure that is independent of any specific programming language or implementation. It is designed to be general-purpose and can be used in various programming languages and applications.

## Characteristics

A pure data structure has several characteristics that distinguish it from other types of data structures:

**Independence:**As mentioned earlier, a pure data structure is not tied to any particular programming language or implementation. It can be implemented in different languages and used across different platforms.**Flexibility:**Pure data structures are versatile and can handle different types of data.They can store integers, floating-point numbers, strings, arrays, or even custom objects.

**Ease of use:**Pure data structures are typically designed with simplicity in mind. They provide straightforward methods for adding, removing, and accessing elements.**Efficiency:**Pure data structures are often optimized for performance. They offer efficient algorithms for searching, sorting, and manipulating the stored data.

## Examples

There are several popular examples of pure data structures:

### The Array

An array is a simple yet powerful pure data structure commonly used in programming. It stores elements in contiguous memory locations and allows random access to its elements using an index.

### The Linked List

A linked list consists of nodes that are connected by pointers. Each node contains data and a pointer to the next node. Linked lists provide efficient insertion and deletion operations.

### The Stack

A stack is a data structure that follows the Last-In-First-Out (LIFO) principle. Elements can only be added or removed from the top of the stack. It is commonly used in programming for tasks such as function calls and expression evaluation.

### The Queue

A queue is a data structure that follows the First-In-First-Out (FIFO) principle. Elements are added at the rear and removed from the front. Queues are often used in scenarios where order matters, such as job scheduling.

## Conclusion

A pure data structure provides a solid foundation for organizing and manipulating data in various programming languages. It offers independence, flexibility, ease of use, and efficiency. Understanding pure data structures is crucial for any programmer looking to optimize their code and create efficient algorithms.
