3 cards from this section. Quick, good the night before a test.
Calculate the distance between the points (3, 4) and (7, 1).
Use the Distance Formula.
If A is (2, 2) and B is (5, 5), can you find the distance between A and B?
What do the coordinates tell you about the distance?
What is the time complexity of the brute-force method to find the closest pair of points?
Think about how many pairs you would check.
Statement: The Distance Formula assumes points have the same coordinates to start. True or False?
What does the formula require for its application?
Consider a set of points: (1, 3), (2, 9), (3, 6), (5, 1), and (7, 8). Apply the divide and conquer method to find the closest pair, detailing your steps.
Remember to only focus on points near the boundary; many distances might not apply.
Given ten random points in a 2D-plane, devise a strategy using the concepts from this section to find the closest pair in the least amount of time.
Efficiency in reducing the search space is crucial.
