2 cards from this section. Quick, good the night before a test.
What is the time complexity of the brute-force method for finding the closest pair of points?
Think about the number of combinations when checking pairs.
Why is sorting necessary in the divide and conquer approach?
Consider how we utilize the x-coordinates.
What is the time complexity of the divide and conquer algorithm for the closest pair of points?
Consider both sorting and the number of comparisons.
True or False: A brute-force solution is sufficient for any number of points.
Think about how performance varies with larger datasets.
Design an efficient algorithm for identifying the closest pair of points in a three-dimensional space and compare it with the two-dimensional solution.
Consider how the layers of data might interact and what modifications you need to track.
Given a large dataset of points, create a visual representation of the divide and conquer process showing how points are divided and sorted.
Think about how you can simplify the visual representation while illustrating the main computational steps.
