Data Structures – Full Course for Beginners

This beginner-friendly course walks you through all the essential data structures—arrays, linked lists (single and doubly), queues, stacks, binary trees (including BSTs), heaps, graphs, and hashing—while showing real-world applications and offering tips for technical interviews and LeetCode practice. Plus, there’s a dedicated video on time complexity analysis to help you understand performance trade-offs.

Chapters are neatly timestamped (arrays at 0:02; linked lists at 0:21 & 0:35; queue at 0:45; stack at 0:58; trees at 1:08 & 1:35; BST at 1:51; heaps at 2:20; graphs at 2:46; hashing at 3:02). If you want extra guidance, you can sign up for 1:1 mentorship through DevLaunch to fast-track your software engineering career.
