Web$\begingroup$ If your data structure doesn't include a list of in-edges for a node, then finding the parent already takes O(m) (in trees hence O(n) time. Since the path to the root of the tree can be linearly long, this is only a quadratic solution. But if you have in-edges, then finding some node with 0 in edges is trivial. $\endgroup$ – baris kebab standバルシュケバブスタンドWebDirected Acyclic Graphs. #. Algorithms for directed acyclic graphs (DAGs).
