WebMar 2, 2024 · Get the directed graph as the input. Perform the DFS on the graph and explore all the nodes of the graph. While exploring the neighbours of the node, add 1 to count and finally return the count which signifies the number of dependencies. Finally, find the node with the minimum number of dependencies. Below is the implementation of the … 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.
