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. WebDec 14, 2024 · Articulation points represent vulnerabilities in a connected network – single points whose failure would split the network into 2 or more components. They are useful for designing reliable networks. For a disconnected undirected graph, an articulation point is a vertex removal which increases the number of connected components. church footwear outlet
