Question 1.
What is Depth-First Search?
Show hintHide hint
Think about how DFS starts its exploration.
Question 2.
Describe what a stack is used for in DFS.
Show hintHide hint
Consider the last vertex added to the stack.
3Question 3.
What does Depth-First Search do?
- Explores all vertices at once
- Explores as far as possible before backtracking
- Is not used for graph traversal
Show hintHide hint
Think about how it approaches exploration compared to BFS.
4Question 4.
Does DFS always find the shortest path in a graph?
- True
- False
Show hintHide hint
Recall how DFS navigates the graph compared to BFS.
Question 5.
Using DFS, find all connected components in a given undirected graph and demonstrate how to apply the algorithm.
Show hintHide hint
Visualize the graph and ensure you revisit all possible starts.
Question 6.
Graph G is constructed with vertices 1-10. Execute DFS and note all pre and post numbers, then identify any cut vertices.
Show hintHide hint
Focus on the connections and transitions between vertices during the DFS process.
