What is the space complexity of Quick Sort in the worst case?

Step 1: Understand what space complexity means. It refers to the amount of memory space required by an algorithm as the input size grows.
Step 2: Know that Quick Sort is a sorting algorithm that uses recursion to sort elements.
Step 3: In Quick Sort, the worst case occurs when the pivot chosen is the smallest or largest element, leading to unbalanced partitions.
Step 4: When Quick Sort is called recursively, each call adds to the stack space used by the program.
Step 5: In the worst case, the depth of the recursion can go up to n (where n is the number of elements), but this is rare.
Step 6: However, on average and in the best case, the depth of recursion is log(n).
Step 7: Therefore, the space complexity in the worst case is O(log n) because we consider the maximum depth of the recursive calls.
