So, why are these data structures you should know? Because they are the most commonly used data structures and form the foundation for efficient algorithm design, problem-solving, and optimizing code performance. Data structures are the fundamental building blocks of computer programming. And understanding them is better for you than grinding out overly complex edge-case leetcode problems. Unless you’re trying to pass a FAANG interview. Which if you’re ever in one and don’t know what data structure to use, just throw a HashMap at it and hope for the best.
