connected graph in data structure
What is a graph data structure?
Graph data structures are a powerful tool for representing and analyzing relationships between objects or entities. Graphs can be used to represent the interactions between different objects or entities, and then analyze these interactions to identify patterns, clusters, communities, key players, influencers, bottlenecks and anomalies.
How do you know if a graph is connected?
Graph G is said to be connected if any pair of vertices (Vi, Vj) of a graph G is reachable from one another. Or a graph is said to be connected if there exists at least one path between each and every pair of vertices in graph G, otherwise, it is disconnected. A null graph with n vertices is a disconnected graph consisting of n components.
