Question 1.
What is the time complexity of the find operation in an array-based implementation?
Show hintHide hint
Think about how quickly you can retrieve the component.
Question 2.
What does the make operation in a union-find data structure do?
Show hintHide hint
Consider what happens to each element initially.
3Question 3.
What is the amortized time complexity for union operations in a pointer-based union-find?
- O(1)
- O(log n)
- O(n)
Show hintHide hint
Think about how unions are formed in the data structure.
4Question 4.
True or False: The find operation can be accomplished in constant time in a pointer-based implementation.
- True
- False
Show hintHide hint
Consider how trees are structured.
Question 5.
Given a union-find data structure with elements 1 through 10, perform a series of unions and a find operation. Calculate the time complexity for each operation based on the implementation type.
Show hintHide hint
Make note of unions performed and the resulting structure.
Question 6.
Design a new optimization technique for union-find and compare it against path compression in terms of efficiency.
Show hintHide hint
Consider methods used in graph algorithms.
