Challenge Problems
Push your limits with advanced challenges
Using DFS, find all connected components in a given undirected graph and demonstrate how to apply the algorithm.
💡 Hint: Visualize the graph and ensure you revisit all possible starts.
Graph G is constructed with vertices 1-10. Execute DFS and note all pre and post numbers, then identify any cut vertices.
💡 Hint: Focus on the connections and transitions between vertices during the DFS process.
