## What is DSA (Data Structures and Algorithms)?

Before exploring the roadmap to learn DSA, let’s understand what DSA is. DSA stands for Data Structures and Algorithms. It refers to computer science's foundational concepts and principles that focus on organizing, storing, and manipulating data efficiently to solve computational problems.

Data Structures: These are specific formats used to organize and store data effectively. Data structures allow for the efficient management, storage, and retrieval of information. Examples include arrays, linked lists, stacks, queues, trees, graphs, hash tables, etc.

Algorithms: Algorithms are step-by-step procedures or sets of instructions designed to perform specific tasks or solve problems. They define a sequence of operations to be executed in a certain order to achieve a desired outcome. Algorithms can range from simple processes like sorting a list of numbers to complex computations like pathfinding in a network.

Understanding data structures and algorithms is fundamental for computer programmers, software engineers, and anyone involved in problem-solving within computer science. Proficiency in DSA enables individuals to develop efficient and optimized solutions for various computational problems, leading to better software performance, faster processing, and more effective utilization of resources.
