WebFeb 7, 2024 · Complexity Analysis: Time Complexity: O(V+E) where V is number of vertices in the graph and E is number of edges in the graph. Space Complexity: O(V). There can be atmost V elements in the stack. So the space needed is O(V). Trade-offs between BFS and DFS: Breadth-First search can be useful to find the shortest path between nodes, and …

WebApr 10, 2024 · This Java program checks whether an undirected graph is connected or not using DFS. It takes input from the user in the form of the number of vertices and edges in the graph, and the edges themselves. It creates an adjacency list to store the edges of the graph, and then uses DFS to traverse the graph and check if all vertices are visited.
