What is the time complexity of the brute-force method for finding the closest pair of points?
💡 Hint: Consider how many total comparisons you must make.
True or False: Sorting the points makes it easier to determine the closest pair by allowing us to check only adjacent points.
💡 Hint: Think about how sorting affects the order of points.

Challenge Problems
Push your limits with advanced challenges
Suppose you have a set of 100 random points in a 2D space. How would you efficiently visualize the divide-and-conquer approach to find the closest points? Provide a detailed approach.
💡 Hint: Use simple drawings to represent the steps.
Consider a set of points where some are very close together and others are widely spaced. What pitfalls might arise in the brute-force approach, and how can divide-and-conquer mitigate these?
💡 Hint: Think about the effectiveness of narrowing down your focus.
