The time complexity of the quicksort algorithm is O(n log n) in the average case and O(n2) in the worst case.
The Big O notation of Quicksort algorithm is O(n log n) in terms of time complexity.
The time complexity of Quicksort algorithm is O(n log n) in terms of Big O notation.
The memory complexity of the quicksort algorithm is O(log n) in the best and average cases, and O(n) in the worst case.
The space complexity of the quicksort algorithm is O(log n) in the best and average cases, and O(n) in the worst case.
The recurrence relation for the quicksort algorithm is T(n) T(k) T(n-k-1) O(n), where k is the position of the pivot element. This relation affects the time complexity of quicksort by determining the number of comparisons and swaps needed to sort the elements. The average time complexity of quicksort is O(n log n), but in the worst-case scenario, it can be O(n2) if the pivot selection is not optimal.

No, quicksort is not a stable sorting algorithm.
The worst-case scenario for the quicksort algorithm using the middle element as the pivot occurs when the array is already sorted or nearly sorted. This can lead to unbalanced partitions and result in a time complexity of O(n2), making the algorithm inefficient.
Quicksort is generally more efficient than heapsort for large datasets due to its average time complexity of O(n log n) compared to heapsort's O(n log n) worst-case time complexity.
The worst-case time complexity of quicksort is O(n2), where n is the number of elements in the array being sorted.
Quicksort is generally more efficient than heapsort for large datasets due to its average-case time complexity of O(n log n) compared to heapsort's O(n log n) worst-case time complexity.
The time complexity of quicksort when the first element is chosen as the pivot is O(n2) in the worst-case scenario.
Insertion sort is a simple sorting algorithm that builds the final sorted array one element at a time. Quicksort is a more complex algorithm that divides the array into smaller sub-arrays and sorts them recursively. Quicksort is generally more efficient for sorting data, as it has an average time complexity of O(n log n) compared to O(n2) for insertion sort.
