What are in-place sorting algorithms?

In-place sorting algorithms sort data without needing extra space for another array. Examples include Quick Sort and Bubble Sort.

How does Quick Sort work as an in-place algorithm?

Quick Sort works by selecting a 'pivot' element and partitioning the array into elements less than and greater than the pivot, then recursively sorting the partitions.

What are the advantages of using in-place sorting?

The main advantages are reduced memory usage and often faster execution since they minimize the overhead of additional data structures.

Can you give me an example of an in-place sorting algorithm in Python?

Sure! Here's a simple implementation of Bubble Sort in Python:

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n-i-1):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr
