Covers the problem of ordering tasks with dependencies, introduces directed acyclic graphs (DAGs) and cycle detection, then explains and compares two canonical algorithms: Kahn's algorithm (using dependency counts and a pending set) and the depth-first search variant. Also discusses adjacency list vs. adjacency matrix graph representations and their trade-offs. Complete Python implementations are provided for both algorithms, including cycle detection. ## Full article daily.dev links to this article rather than hosting it.
