Quicksort Algorithm [with Animated Example]

In this video, I will show you how Quick Sort works - and how you can determine the Quicksort time complexity without complicated math.
I explain the Quicksort algorithm with an example, using animations and visualizations. I show you visually how to determine the time complexity and what "quasilinear time" - O(n log n) - means for algorithms.
On my blog, you can learn how to implement Quicksort in Java and how "Dual-Pivot Quicksort" works:

This video helped me understand Quick Sort Algorithm better than other resources online. Thanks for the explanation!

[@shabeerahamed2129]

great explanation👏

Hi! Could you please tell me how do you make animations for your videos, what soft do you use?

Hi, I used to use DaVinci Resolve but recently switched to Premiere Pro. Both are not perfect and tend to get pretty slow when you have a lot of elements, but Premiere Pro is significantly faster than DaVinci Resolve.
