Which traversal method is typically used for finding connected components in an undirected graph?
Step 1: Understand what a connected component is. A connected component in an undirected graph is a set of vertices such that there is a path between any two vertices in this set.
Step 2: Know that there are two common methods to explore graphs: Breadth-First Search (BFS) and Depth-First Search (DFS).
Step 3: Choose a starting vertex from the graph that you want to explore.
Step 4: Use either BFS or DFS to explore all the vertices that can be reached from the starting vertex.
Step 5: Mark all the visited vertices during the exploration. These vertices form one connected component.
Step 6: Repeat steps 3 to 5 for any unvisited vertex in the graph until all vertices have been visited. Each time you start from an unvisited vertex, you will find a new connected component.
