What algorithmic technique does the closest pair problem use?
💡 Hint: Think about how we break down the problem into smaller pieces.
True or False: The closest pair algorithm can only be applied if all points have unique coordinates.
💡 Hint: Consider how duplicates may or may not affect overall results.

Challenge Problems
Push your limits with advanced challenges
You're given six points: A(1, 1), B(1, 3), C(4, 2), D(5, 1), E(2, 4), F(3, 5). Apply the closest pair algorithm to find the closest pair. Show your working.
💡 Hint: Run through the algorithm step-by-step, sorting first and checking adjacent pairs.
Imagine applying a nearest neighbor technique for a group of 10 random points. Propose a method that ensures the algorithm stays efficient and does not revert to O(n²) even with duplicates.
💡 Hint: Think about leveraging both sorting and efficient data structures.
