Question 1.
What is the naive approach to finding the closest pair of points?
Show hintHide hint
Think about how many comparisons you need to make.
Question 2.
What does 'divide and conquer' mean?
Show hintHide hint
Remember the steps: split, solve, combine.
3Question 3.
What is the time complexity of the naive approach in finding the closest pair of points?
- O(n)
- O(n^2)
- O(n log n)
Show hintHide hint
How many pairs are there for n points?
4Question 4.
True or False: The divide and conquer approach guarantees an optimal solution.
- True
- False
Show hintHide hint
What does 'guarantee' mean in terms of algorithm results?
Question 5.
Given a set of random points, implement the divide and conquer algorithm to find the closest pair and explain each step taken.
Show hintHide hint
Refer back to each step in the process.
Question 6.
Discuss the trade-offs when implementing the closest pair problem for 1D and 2D datasets. What complexities arise?
Show hintHide hint
Consider spatial dimensions and their implications.
