Quick Sort Complexity | Dataford Interview Questions

Implement a quick sort algorithm and explain its time and space complexity.

Implement quick_sort(arr) to sort an array of integers in ascending order. The function should sort the input list in place and return the same list. Do not call Python's built-in sorting functions. Explain the partition strategy and the average and worst-case time and auxiliary space complexity.

Constraints

0 <= len(arr) <= 1000
-10^9 <= arr[i] <= 10^9
Sort the list in place
Do not use built-in sorting functions

Function Signature
