There is a cycle in a graph only if there is a back edge present in the graph. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. Missing number in array. A directed graph is graph, i.e., a set of objects (called vertices or nodes) that are connected together, where all the edges are directed from one vertex to another.A directed graph is sometimes called a digraph or a directed network.In contrast, a graph where the edges are bidirectional is called an undirected graph.. To detect a back edge, keep track of . Your task is to complete the function isCyclic() which takes the integer V denoting the number . Directed graphs are the most general kind of graphs because they don't impose the restrictive assumption of symmetry in the relationship modeled by the edges.
