Challenge Problems
Push your limits with challenges.
Question 1
Given an array of integers that are sorted in decreasing order, analyze the performance of Quicksort based on different pivot choices. Discuss the implications.
💡 Hint: Focus on how poor pivot choice impacts eventual partitioning.
Question 2
Design and implement a randomized Quicksort algorithm in pseudocode. Explain how it mitigates worst-case time complexity.
💡 Hint: Consider how randomness influences partitioning hence affects runtime.
