Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/kharzixen/data-structures-and-algorithms

This project is dedicated to implementing a variety of fundamental data structures and algorithms in C++ for educational purposes. The goal is to enhance my understanding of core computer science concepts through hands-on coding and problem-solving.
