TL;DR

Tim’s free full-course for beginners breaks down core data structures—starting with arrays and time complexity, then moving through single & doubly linked lists, queues, stacks, binary trees (and BSTs), heaps, graphs, and hashing. Every section has handy timestamps so you can jump right to what you need.

Plus, there’s a bonus deep dive on time complexity analysis and an offer to join DevLaunch’s one-on-one mentorship program for hands-on interview prep and real-world coding practice.
