Welcome to Part 23 of Code & Debug’s DSA in Python Course! 🎉 In this video, we’ll cover Quick Sort, one of the fastest and most efficient sorting algorithms, and implement it step-by-step in Python. Mastering Quick Sort is essential for understanding advanced sorting techniques in Data Structures and Algorithms (DSA).
Here’s what you’ll learn:
📌 What is Quick Sort, and how does it work?
📌 Step-by-step explanation of the divide-and-conquer approach
📌 Python implementation with practical examples
