Challenge Problems
Push your limits with advanced challenges
Given five points in a 2D space: (1,2), (3,1), (4,4), (5,3), and (2,5). Find the closest pair and use the divide and conquer method to justify your steps.
💡 Hint: Carefully consider step-by-step pair comparisons both within each half and the band across the dividing line.
How would you implement a function to perform the closest pair calculation on an arbitrary number of points?
💡 Hint: Start with establishing base case handling and ensure effective recursion.
