Question 1.
What is the average-case time complexity of Quicksort?
Show hintHide hint
Think about how the array gets divided on average.
Question 2.
What is a pivot in the context of Quicksort?
Show hintHide hint
It's the element that divides the array into two parts.
3Question 3.
What is the average case time complexity of Quicksort?
- O(n)
- O(n log n)
- O(n²)
Show hintHide hint
Affected by how evenly the array gets divided.
4Question 4.
True or False: The worst-case scenario of Quicksort occurs when the pivot is always the median.
- True
- False
Show hintHide hint
Consider what happens with sorted arrays.
Question 5.
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.
Show hintHide hint
Focus on where each element should go relative to the pivot.
Question 6.
Design a randomized Quicksort and explain how your pivot selection helps mitigate worst-case scenarios while considering a worst-case input.
Show hintHide hint
Think about how random choices can alter expected performance.
