More formally a Graph can be defined as, A Graph consists of a finite set of vertices(or nodes) and set of Edges which connect a pair of nodes. Take a look at the following graph − C++ Server Side Programming Programming The adjacency list representation of a graph is linked list representation. For example, in Facebook, each person is represented with a vertex(or node). (4 -> 5) Path: A sequence of edges that allows you to go from vertex A to vertex B is called a path. A standard BFS implementation puts each vertex of the graph into one of two categories: 1. Visited 2. C/C++ Program for Find if there is a path between two vertices in a directed graph. Must … 2.
