WebSo, we need to increment the component count and visit all the nodes part of the component using DFS. Steps: First, mark all vertices as unvisited. Iterate over all vertices. If a vertex is not visited, perform DFS on that vertex and increment the count by 1. After iterating over all vertices, the value of count will be the number of connected ... WebNov 18, 2024 · A vertex is said to be an articulation point in a graph if removal of the vertex and associated edges disconnects the graph. So, the removal of articulation points increases the number of connected components in a graph. Articulation points are sometimes called cut vertices. The main aim here is to find out all the articulations points …
