Python 3: Project-based Python, Algorithms, Data Structures - A look at the recursive divide function

The video tutorial covers the implementation of the Quicksort algorithm in Python. It begins with an overview of the algorithm and the choice of pivot, followed by setting up a Python script. The instructor explains the base case and demonstrates how to select the pivot using the last element of the list. The video then details the creation of three lists: smaller, equal, and larger, and how to populate them based on the pivot. The tutorial shows how to return these lists and convert them into a single list by concatenation. Finally, the video demonstrates the recursive implementation of Quicksort, resulting in a sorted list. The instructor encourages viewers to try an in-place implementation for further learning.

What is the significance of using the last element as the pivot in the Quicksort algorithm?

What changes are made to return a single list instead of a tuple of three lists?

Discuss the educational purpose of implementing Quicksort in a simpler way with three lists.
