Graph connectivity c++
WebMar 14, 2024 · A graph where all vertices are connected with each other has exactly one connected component, consisting of the whole graph. Such a graph with only one connected component is called a Strongly Connected Graph. This problem can be easily solved by applying DFS() on each component. In each DFS() call, a component or a sub … WebFeb 7, 2024 · To count number of groups, we need to simply count connected components in the given undirected graph. Counting connected components can be easily done using DFS or BFS . Since this is an undirected graph, the number of times a Depth First Search starts from an unvisited vertex for every friend is equal to the number of groups formed.
