Question 1.
What does the find operation do in Union-Find?
Show hintHide hint
Think about how you check for a group or a team.
Question 2.
How does the union operation affect two disjoint sets?
Show hintHide hint
Imagine combining two groups into one larger group.
3Question 3.
What is the primary function of the union operation?
- A) To find the size of a component
- B) To split a component into two
- C) To merge two components
- D) To check if elements are in the same component
Show hintHide hint
Think about what happens during a team merger.
4Question 4.
True or False: Path compression only applies during the union operation.
- True
- False
Show hintHide hint
Remember where path compression is most helpful.
Question 5.
Given a list of edges in a graph, demonstrate how the Union-Find structure can be used to detect cycles.
Show hintHide hint
Start with each vertex in its own set, and apply union carefully.
Question 6.
Develop an alternative implementation of Union-Find that uses linked lists instead of arrays, and analyze its efficiency.
Show hintHide hint
Think about the operations in linked lists and how to traverse them.
