Q. In which scenario would Dijkstra's algorithm be most useful?
A.
Finding the maximum element in an array
B.
Calculating the shortest distance between cities on a map
C.
Sorting a list of names alphabetically
D.
Searching for a specific value in a linked list
Solution
Dijkstra's algorithm is most useful for calculating the shortest distance between cities on a map, as it efficiently finds the shortest paths in weighted graphs.
Correct Answer:
B
— Calculating the shortest distance between cities on a map
Q. In which scenario would K-means clustering be preferred over hierarchical clustering?
A.
When the number of clusters is unknown
B.
When computational efficiency is a priority
C.
When the data is not well-separated
D.
When a detailed cluster hierarchy is needed
Solution
K-means clustering is preferred when computational efficiency is a priority, especially for large datasets, as it is generally faster than hierarchical clustering.
Correct Answer:
B
— When computational efficiency is a priority
Q. In which scenario would you prefer a Red-Black Tree 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
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 require fewer rotations to maintain balance compared to AVL Trees.
Correct Answer:
A
— When frequent insertions and deletions are expected
Q. In which scenario would you prefer using a Red-Black tree 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
D.
When search operations are the most frequent
Solution
Red-Black trees are generally preferred when there are frequent insertions and deletions because they require fewer rotations to maintain balance compared to AVL trees.
Correct Answer:
A
— When frequent insertions and deletions are expected
