DSA Fundamentals — Codemia

This course teaches algorithmic patterns, not memorization. Once you recognize a pattern, you can adapt it to any variant in an interview.

The course covers 27 algorithmic patterns organized into 8 chapters, from foundational techniques through advanced topics. Each lesson explains why a pattern works, demonstrates it with animated visualizations, and then provides 2–3 problems to solve in an embedded code editor.
