Question 1.
What are the two parts of a node in the union-find data structure?
Show hintHide hint
Think about how each element relates to other components.
Question 2.
Define path compression in simple terms.
Show hintHide hint
Consider how it impacts node connections after a search.
3Question 3.
What does a node in the union-find structure represent?
- A single element
- A component
- Both a and b
Show hintHide hint
Remember the structure of a node.
4Question 4.
True or False: Path compression can only be applied once during a find operation.
- True
- False
Show hintHide hint
Consider how nodes are adjusted during traversal.
Question 5.
Given a set of elements {1, 2, 3, 4, 5}, illustrate the union-find operations after performing unions (1,2) and (3,4). Followed by a union (2,4). Construct the final structure.
Show hintHide hint
Start by visualizing the connections after each union.
Question 6.
Explain how amortized analysis is done for the union-find structure. What can we conclude about time complexities per operation?
Show hintHide hint
Consider approximating over multiple sequences rather than single operations.
