Question 1.
What is the brute force approach to the closest pair problem?
Show hintHide hint
Think about how many combinations of pairs there are.
Question 2.
Define what is meant by 'divide and conquer' in algorithms?
Show hintHide hint
Consider how you could solve a big problem by breaking it down.
3Question 3.
What is the maximum time complexity of the closest pair of points using the divide and conquer method?
- O(n²)
- O(n log n)
- O(n)
Show hintHide hint
Think about the efficiency gained when using sorting.
4Question 4.
True or False: Boundary candidates are irrelevant in finding the closest pair of points.
- True
- False
Show hintHide hint
Consider if points only on one side could be the closest.
Question 5.
If you were tasked with adapting the closest pair algorithm for a dynamic dataset where points can be added or removed frequently, how would you approach this problem?
Show hintHide hint
Consider the implications of real-time changes on your sorting and dividing strategy.
Question 6.
Develop a hypothetical scenario where the divide and conquer approach to closest pair would perform poorly compared to a brute-force approach.
Show hintHide hint
Identify conditions under which sorting may not yield a straightforward advantage.
