WebAug 18, 2024 · Finding connected components using DFS Conclusion Introduction Graphs and Trees are some of the most important data structures we use for various applications in Computer Science. They represent data in the form of nodes, which are connected to other nodes through ‘edges’.

In graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets. A graph that is itself connected has exactly one component, consisting of the whole graph. Components are sometimes called connected components.
