Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What effect does sorting the points have on the closest pair algorithm?

  • A. It decreases time complexity
  • B. It is unnecessary
  • C. It causes the points to overlap

💡 Hint: Think about how you would approach finding the closest points without sorting.

Question 2

Is the closest pair algorithm based on divide and conquer?

  • True
  • False

💡 Hint: Recall the key strategy we discussed.

Challenge Problems

Push your limits with challenges.

Question 1

Given the coordinates of 10 points in a 2D plane, visualize their positions and demonstrate the divide-and-conquer steps you would take to find the closest pair.

💡 Hint: Focus on groups of points and how they might interact on either side of the dividing line.

Question 2

Create a real-world scenario where finding the closest pair would be advantageous. Describe how you would implement the algorithm while considering limitations.

💡 Hint: Think of a dynamic or changing environment, like a delivery service.
