Question 1

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)

💡 Hint: Think about the efficiency gained when using sorting.

Question 2

True or False: Boundary candidates are irrelevant in finding the closest pair of points.

  • True
  • False

💡 Hint: Consider if points only on one side could be the closest.

Challenge Problems

Push your limits with challenges.

Question 1

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?

💡 Hint: Consider the implications of real-time changes on your sorting and dividing strategy.

Question 2

Develop a hypothetical scenario where the divide and conquer approach to closest pair would perform poorly compared to a brute-force approach.

💡 Hint: Identify conditions under which sorting may not yield a straightforward advantage.
