WebThe usual name for such a digraph is directed acyclic graph (DAG). Multitrees are DAGs in which there are no two distinct directed paths from the same starting vertex to the same ending vertex.

Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle. list the files in a directory cmd
