Q. Which of the following is NOT a characteristic of a good hash function?
A.
Deterministic
B.
Uniform distribution
C.
Fast computation
D.
Produces a sorted output
Solution
A good hash function should be deterministic, provide a uniform distribution of hash values, and be fast to compute, but it does not need to produce a sorted output.
Q. Which of the following is NOT a common application of Disjoint Set Union?
A.
Kruskal's algorithm for minimum spanning tree
B.
Network connectivity
C.
Dynamic connectivity queries
D.
Binary search tree operations
Solution
Binary search tree operations are not a common application of Disjoint Set Union; it is primarily used for network connectivity and algorithms like Kruskal's.
Q. Which of the following is NOT a typical application of Disjoint Set Union?
A.
Network connectivity
B.
Kruskal's algorithm for minimum spanning tree
C.
Finding the shortest path in a graph
D.
Image processing for region labeling
Solution
Finding the shortest path in a graph is not a typical application of Disjoint Set Union; it is more related to algorithms like Dijkstra's or Bellman-Ford.
Correct Answer:
C
— Finding the shortest path in a graph
Q. Which of the following techniques can be used to optimize the Union operation in Disjoint Set Union?
A.
Path compression
B.
Binary search
C.
Heapification
D.
Graph traversal
Solution
Path compression is a technique used to optimize the Union operation in Disjoint Set Union by flattening the structure of the tree whenever 'Find' is called.
