Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given 10 random points, explain step-by-step how the closest pair would be determined using the divide and conquer approach while providing specific distance calculations.

💡 Hint: Remember to calculate distances as you compare candidates.

Challenge 2 Hard

In a dataset of 50 random points, simulate the divide and conquer approach and describe how many pairwise distance checks would be required versus using a naive method.

💡 Hint: Use the formula for combinations to count pairs: n(n-1)/2.
