Show hintHide hint
Think about real-world applications.
Question 2.
What is the naive approach to solving the closest pair problem?
Show hintHide hint
Consider how many pairs there are.
3Question 3.
What is the time complexity of the naive closest pair algorithm?
- O(n log n)
- O(n)
- O(n²)
Show hintHide hint
Consider the number of pairs formed with n points.
4Question 4.
True or False: The divide and conquer method reduces the time complexity of the closest pair problem.
- True
- False
Show hintHide hint
Think about efficiency gains.
Question 5.
Given a set of 10 random (x, y) coordinates, implement the divide and conquer algorithm to find the closest pair. Explain each step you took in solving the problem.
Show hintHide hint
Think of how sorting aids in your recursive splits.
Question 6.
Design a scenario where the naive closest pair algorithm could significantly lag behind the divide and conquer method, quantifying the difference in time taken for n=1000 points.
Show hintHide hint
Compare computational efforts of both approaches in practical terms.
