Q. In which scenario is Breadth-First Search (BFS) preferred over Depth-First Search (DFS)?
A.
When memory is limited
B.
When the shortest path is required
C.
When the graph is very deep
D.
When cycles are present
Solution
BFS is preferred when the shortest path is required because it explores all neighbors at the present depth prior to moving on to nodes at the next depth level.
Correct Answer:
B
— When the shortest path is required
Q. In which scenario would a linked list be preferred over an array?
A.
When the size of the data is known
B.
When frequent insertions and deletions are required
C.
When random access is needed
D.
When memory is limited
Solution
Linked lists are preferred when frequent insertions and deletions are required because they can be done in O(1) time, unlike arrays which require O(n) time.
Correct Answer:
B
— When frequent insertions and deletions are required
Q. In which scenario would a Red-Black tree be preferred over an AVL tree?
A.
When frequent insertions and deletions are expected.
B.
When memory usage is a critical factor.
C.
When the dataset is static and does not change.
D.
When the tree needs to be perfectly balanced.
Solution
Red-Black trees are generally preferred when there are frequent insertions and deletions because they are less rigidly balanced than AVL trees, allowing for faster insertions and deletions.
Correct Answer:
A
— When frequent insertions and deletions are expected.
Q. In which scenario would an AVL tree be preferred over a Red-Black tree?
A.
When insertions and deletions are more frequent than searches.
B.
When search operations are more frequent than insertions and deletions.
C.
When memory usage is a concern.
D.
When the dataset is small.
Solution
AVL trees are preferred when search operations are more frequent than insertions and deletions because they provide faster search times due to stricter balancing.
Correct Answer:
B
— When search operations are more frequent than insertions and deletions.
Q. In which scenario would BFS be preferred over DFS?
A.
Finding the shortest path in an unweighted graph
B.
Finding a path in a maze
C.
Topological sorting
D.
Finding connected components
Solution
BFS is preferred for finding the shortest path in an unweighted graph because it explores all neighbors at the present depth prior to moving on to nodes at the next depth level.
Correct Answer:
A
— Finding the shortest path in an unweighted graph
