4.2. Space Complexity Basic implementations of quicksort have a space complexity ofO(log n)for recursive calls. However, in a worst-case scenario, where the partition function creates a skewed partition, the space complexity can reachO(n). Best case: O(log n) Average case: O(log n) Worst...
Space Complexity(From wiki). Quicksort with in-place and unstable partitioning uses only constant additional space before making any recursive call. Quicksort must store a constant amount of information for each nested recursive call. Since the best case makes at mostO(logn) nested recursive calls,...

In the main method, we create a sample array, print it, sort it using QuickSort, and then print the sorted array. Time Complexity Best and Average case: O(n log n) Worst case: O(n^2) (rare, occurs when the pivot is always the smallest or largest element) Space Complexity: O(log...
Comparing the mergesort and quicksort, the mergesort needs O(n) space complexity to realize, while quicksort doesn't need it, for the exchange is utilised here. However, the space complexity is log n, for a stack is necessary for its recursion. ...
Quicksort is generally an in-place sorting algorithm, meaning it does not require additional memory proportional to the input size. The space complexity is O(log n) due to the recursion stack space required to maintain the call stack during the sorting process. ...
Space Complexity The average-case space complexity for the quick sort algorithm isO(Logn). It is the space required by the recursion stack. But in the worst-case when sorting an array requiresnrecursive, the space complexity isO(n).
