Question 1.
What is the average-case time complexity of Quicksort?
Show hintHide hint
Think about how often the algorithm runs effectively on typical inputs.
Question 2.
What is a pivot in the context of Quicksort?
Show hintHide hint
It's crucial for the sorting process.
3Question 3.
What is the worst-case time complexity of Quicksort?
- O(n)
- O(n log n)
- O(n²)
Show hintHide hint
Think about how a sorted array would behave.
4Question 4.
True or False: The average-case complexity of Quicksort is worse than that of Merge sort.
- True
- False
Show hintHide hint
Compare their average performance across typical inputs.
Question 5.
You have an array of random integers. Write a pseudocode for an iterative version of Quicksort.
Show hintHide hint
What data structure would you typically use for managing segments?
Question 6.
Explain why randomization improves Quicksort performance. Provide an example involving a specific input.
Show hintHide hint
How does the location of the pivot affect sorting efficiency?
