Yes, Quicksort is implemented in place, meaning it sorts the elements within the original array without requiring additional memory for a separate copy of the data.
No, quicksort is not a stable sorting algorithm.
To implement the quicksort algorithm with a 3-way partition in Java, you can modify the partitioning step to divide the array into three parts instead of two. This involves selecting a pivot element and rearranging the elements so that all elements less than the pivot are on the left, all elements equal to the pivot are in the middle, and all elements greater than the pivot are on the right. This approach can help improve the efficiency of the quicksort algorithm for arrays with many duplicate elements.

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.

quicksort
Quicksort is a popular algorithm to sort items in software, aiming at completion in the smallest number of steps (shortest time) possible.
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 time complexity of the quicksort algorithm is O(n log n) in the average case and O(n2) in the worst case.
The worst-case time complexity of quicksort is O(n2), where n is the number of elements in the array being sorted.
implemented
The time complexity of quicksort when the first element is chosen as the pivot is O(n2) in the worst-case scenario.
