Question 1.
What does it mean for two vertices to be strongly connected?
Show hintHide hint
Think about both directions of travel.
Question 2.
What type of search algorithm is primarily used to find SCCs?
Show hintHide hint
Recall the deep exploration technique.
3Question 3.
What does it mean for a graph to have strongly connected components?
- Every vertex can reach every other vertex.
- There are no edges.
- The graph is acyclic.
Show hintHide hint
Consider the definition of strong connectivity.
4Question 4.
Is a back edge in DFS indicative of a cycle in a graph?
- True
- False
Show hintHide hint
Think about the directionality of edges.
Question 5.
Given a directed graph with vertices A, B, C, and edges (A -> B), (B -> C), (C -> A), identify all SCCs and classify edges.
Show hintHide hint
Visualize or draw the graph to better understand the connections.
Question 6.
For a directed graph example: A -> B, B -> C, C -> D, and D -> B, analyze the edges and determine the presence of SCC.
Show hintHide hint
Trace the paths to verify strong connectivity in the graph.
