Best Algorithms & Data Structures Courses

Berkeley's data structures course — one of the best undergraduate CS courses available free online. Rigorous theoretical treatment with practical Java implementations.

Pattern-based interview prep with structured video explanations for every problem category. More efficient than raw LeetCode grinding — teaches you to recognise patterns, not memorise solutions.

MIT's foundational algorithms course — covers the same material as CLRS with lecture videos, problem sets, and exams. The academic gold standard for algorithm education.

Pattern-based interview prep with structured video explanations for every problem category. More efficient than raw LeetCode grinding — teaches you to recognise patterns, not memorise solutions.

Curated set of 160 interview problems with video solutions in multiple languages. Less volume than LeetCode, more explanation depth — good if you prefer quality over quantity.
