Data Structures Questions
A directed acyclic graph (DAG) is a graph that contains directed edges between nodes, but does not contain any cycles. This means that there is no way to start at a node and follow a sequence of directed edges to return back to the same node. On the other hand, a cyclic graph contains at least one cycle, which is a sequence of edges that allows you to start at a node and follow a path to return back to the same node. In other words, a cyclic graph has a loop or a circular path, while a directed acyclic graph does not.
