Challenge Problems
Push your limits with challenges.
Question 1
Given the array [60, 20, 90, 10, 50], implement a Quicksort function that sorts it in ascending order and explain each step of the recursive process.
💡 Hint: Track how the pivot influences the partitioning process at each recursive step.
Question 2
Create a scenario showing how Quicksort can lead to inefficient sorting. Use specific examples of pivot selection that could lead to worst-case performance.
💡 Hint: Visualize the consequences of poor pivot choices over several recursive layers.
