Question 1
What is the worst-case time complexity of Quicksort?
- O(n log n)
- O(n²)
- O(n)
💡 Hint: Reflect on cases where the pivot choice leads to unbalanced splits.
Question 2
Average-case performance of Quicksort is O(n log n). True or False?
- True
- False
💡 Hint: Think about how it performs on most random inputs.

Challenge Problems
Push your limits with challenges.
Question 1
Design an example input for Quicksort that results in the worst-case performance. Explain your reasoning.
💡 Hint: Consider how the partitioning impacts the subsequent recursive calls.
Question 2
Transform the provided Quicksort pseudocode into an iterative form using a stack. Explain how stack operations mirror recursive calls.
💡 Hint: Trace through the recursive calls to see how they'd translate into managing state on a stack.
