Question 1.
What does DFS stand for?
Show hintHide hint
Think about the approach it takes in exploration.
Question 2.
Describe the primary data structure used by DFS.
Show hintHide hint
Consider how it keeps track of nodes.
3Question 3.
What is the primary goal of Depth-First Search?
- To find all solutions
- To explore all nodes at current level
- To explore as far as possible along branches
Show hintHide hint
Think about what the 'depth-first' refers to.
4Question 4.
True or False: Depth-First Search guarantees an optimal solution.
- True
- False
Show hintHide hint
Reflect on the conditions under which it operates.
Question 5.
Consider a scenario where you have a graph representing a complex city with multiple paths. Design a DFS algorithm to find a route to a specific location. Discuss its efficiency and potential pitfalls.
Show hintHide hint
Think about how backtracking would work here.
Question 6.
Evaluate the effectiveness of DFS in a large data structure compared to BFS. Provide a real-world example where these differences are crucial.
