Question 1.
Define a connected graph.
Show hintHide hint
Think about how vertices are grouped.
Question 2.
What is a cycle in a graph?
Show hintHide hint
Consider paths that revisit nodes.
3Question 3.
What is the main purpose of BFS?
- To explore all vertices and edges in a graph
- To sort the vertices of a graph
- To find the shortest path between two vertices
Show hintHide hint
Think about its primary function in graph exploration.
4Question 4.
True or False: A cycle can exist if there are no non-tree edges during BFS.
- True
- False
Show hintHide hint
Consider the definition of cycles.
Question 5.
Given a disconnected graph, devise an algorithm using BFS to identify all connected components. How would you ensure each component is labeled correctly?
Show hintHide hint
Consider using an additional array to track the component labels.
Question 6.
How could you efficiently find articulation points in a graph using DFS? Provide pseudo-code for your approach.
Show hintHide hint
Reflect on how vertices relate to their children in a DFS tree.
