Question 1.
What is a connected component?
Show hintHide hint
Think of it as a group in a family tree.
Question 2.
Name the two algorithms discussed for exploring graphs.
Show hintHide hint
One goes level by level, the other dives deep.
3Question 3.
What is a connected component?
- A set of isolated vertices
- A subset of vertices where every vertex is reachable from every other vertex
- Any connected subgraph
Show hintHide hint
Think about how planets might be grouped based on their orbits.
4Question 4.
True or False: A connected graph has no disconnected components.
- True
- False
Show hintHide hint
Consider the definition of connectivity.
Question 5.
Given a complex undirected graph with isolated vertices and connected components, explain how you would identify and label each component.
Show hintHide hint
Consider sorting your visit order by the vertex number for systematic labeling.
Question 6.
Write a function to determine if a given undirected graph contains cycles using DFS. What parameters would you pass?
Show hintHide hint
Focus on backtracking and how visited nodes are tracked.
