Question 1
What is the average case time complexity of Quicksort?
- O(n)
- O(n log n)
- O(n²)
💡 Hint: Affected by how evenly the array gets divided.
Question 2
True or False: The worst-case scenario of Quicksort occurs when the pivot is always the median.
- True

Challenge Problems
Push your limits with challenges.
Question 1
Given the array [7, 2, 1, 6, 8, 5, 3, 4], manually apply the Quicksort algorithm by choosing the first element as the pivot through two partitions.
💡 Hint: Focus on where each element should go relative to the pivot.
Question 2
Design a randomized Quicksort and explain how your pivot selection helps mitigate worst-case scenarios while considering a worst-case input.
💡 Hint: Think about how random choices can alter expected performance.
