Can you explain how the quicksort algorithm works?
Sure! Quicksort is a divide-and-conquer algorithm that sorts an array by selecting a 'pivot' element.
How does the pivot selection affect the sorting process?
The choice of pivot can significantly impact performance. A good pivot divides the array into balanced parts.
What are the average and worst-case time complexities of quicksort?
The average time complexity is O(n log n), while the worst-case is O(n²), which occurs with poor pivot choices.
Can you give me a simple example of how quicksort works?
Absolutely! For example, if we have an array [3, 6, 8, 10, 1, 2, 1], we might choose 6 as the pivot.
