Can you help me understand sorting algorithms?

Can you help me understand sorting algorithms?

Sure! Sorting algorithms are methods for arranging elements in a specific order. Do you have a specific algorithm in mind?

What about quicksort? How does it work?

Quicksort is a divide-and-conquer algorithm. It selects a 'pivot' element and partitions the array into two sub-arrays, sorting them recursively.

What is the time complexity of quicksort?

The average time complexity of quicksort is O(n log n), but in the worst case, it can be O(n²) if the pivot is poorly chosen.

Can you give me an example of quicksort in Python?

Absolutely! Here's a simple implementation:

def quicksort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x < pivot]
    middle = [x for x in arr if x == pivot]
    right = [x for x in arr if x > pivot]
    return quicksort(left) + middle + quicksort(right)

This function sorts an array using quicksort.
