Check if a digraph is a DAG (Directed Acyclic Graph) or not

WebA connected acyclic graph is called a tree. In other words, a connected graph with no cycles is called a tree. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes. A tree with ‘n’ vertices has ‘n-1’ edges.
