Which algorithm is best suited for finding connected components in a graph?
Step 1: Understand what a graph is. A graph consists of nodes (or vertices) and edges that connect them.
Step 2: Know what connected components are. A connected component is a subset of the graph where there is a path between any two nodes in that subset.
Step 3: Learn about Depth-First Search (DFS). DFS is a method for exploring a graph by starting at a node and exploring as far as possible along each branch before backtracking.
Step 4: Start DFS from an unvisited node. Mark this node as visited.
Step 5: Explore all adjacent nodes (connected nodes) from the current node using DFS. Mark each visited node.
Step 6: Repeat steps 4 and 5 until all nodes in the connected component are visited.
Step 7: Once you finish exploring one connected component, start again from another unvisited node to find the next connected component.
Step 8: Continue this process until all nodes in the graph have been visited and all connected components have been identified.
