WebNov 24, 2016 · Given a directed graph, check if it is a DAG (Directed Acyclic Graph) or not. A DAG is a digraph (directed graph) that contains no cycles. The following graph contains a cycle 0—1—3—0, so it’s not DAG. If we remove edge 3–0 from it, it will become a DAG. For an edge u —> v in a directed graph, an edge is a tree edge if parent[v] = u. For … WebOct 22, 2024 · Given a directed acyclic graph G, give a linear time algorithm to determine if the graph has a directed path that visits every vertex.
