WebDFS algorithm explores the graph by traversing as far as possible along each branch before backtracking. In this case, DFS starts at node A and then follows the edge to node B. From B, it explores the first edge to C, then moves to D, and finally to E. WebBFS is also useful for finding the level or depth of each node in the graph, whereas DFS is better for finding the topological order or post-order of the graph. Additionally, BFS should...
