Data Structures and Algorithms

Data Structures and Algorithms (DSA) is a fundamental concept in computer science that involves the organization, management, and storage of data in a way that enables efficient access and modification. Data structures, such as arrays, linked lists, stacks, queues, trees, and graphs, provide the means to structure data for optimal performance. Algorithms are step-by-step procedures or formulas for solving specific problems, enabling tasks such as searching, sorting, and manipulating data. Understanding DSA is crucial for software development, as it impacts the efficiency, performance, and scalability of programs and systems. Mastery of DSA is essential for technical problem-solving and is a key focus in coding interviews.
