This beginner-friendly crash course walks you through all the essentials of data structures—starting from arrays and linked lists to stacks, queues, trees, graphs, heaps and hashing—while showing you how each one applies to real-world coding, technical interviews or LeetCode challenges. Chapters are neatly timestamped so you can dive straight into whichever topic you need.
Along the way you’ll find a quick link to a deeper mentorship program (DevLaunch) if you’re hunting for one-on-one support landing a software engineering gig, plus an extra video on time complexity analysis to sharpen your Big O game.
