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.
