Challenge Problems
Push your limits with challenges.
Question 1
Given a graph with vertices and edges, implement DFS and identify the pre and post numbers for each vertex. How do these numbers help in identifying cycles?
💡 Hint: Look for revisits in your traversal log.
Question 2
Consider a scenario where you have to analyze a social network graph for strong connectivity. Use DFS with pre and post numbers to determine critical nodes whose removal would disconnect the network.
💡 Hint: Check which nodes are revisited and how their removal affects connectivity in your DFS traversal.
