Скачать или смотреть Master QuickSort in Minutes! Randomized, QuickSelect & 3 Way Sorting Explained Simply

Learn one of the most powerful and elegant algorithms in computer science — QuickSort!
In this video, we’ll explore how the randomized quicksort algorithm works, analyze its performance, and then dive into its smart variants:

🔹 Randomized QuickSort – Improves performance by eliminating worst-case input patterns.
🔹 QuickSelect – A brilliant modification of quicksort that finds the kth smallest element in linear time.
🔹 3-Way QuickSort – The perfect solution for handling duplicate keys efficiently.

You’ll understand:
✅ How partitioning works step-by-step
✅ Why randomization improves average performance
✅ How QuickSelect differs from sorting entirely
✅ When to use 3-way partitioning

Whether you’re preparing for coding interviews, studying data structures & algorithms, or just love algorithmic problem-solving, this tutorial is a must-watch!
