A Complete Overview of Quicksort (Data Structures & Algorithms #11)

Here's my introduction to / overview of the quicksort / quick sort algorithm!
Patreon: csdojo.io/pat
The book I mentioned (referral link): amzn.to/3j6e6wN
My sample code: www.csdojo.io/quick
3-way quicksort: www.geeksforgeeks.org/3-way-q...

I love how you hide all the code to avoid overwhelming

[@TharaMesseroux1]

Me too! It makes it so much easier to understand! Thank you CSDojo!

[@retr0477]

Man I’m so glad that you decided to continue these series. I love these series. So educational and so simple unlike other textbooks. Please keep these going. Thanks YK.

Sometimes he knowingly makes mistake to teach how to deal with it. Salute to him

[@JavarevisitedTech]

that's actually a great way to teach, it provokes your mind to learn more.

[@DevsLikeUs]

Most great teachers do it, he's really good.

I love the way u teach. Pls continue this series...

[@raevenbauto1578]

Please continue to make data structures and algorithms simple. Among all the videos I watched this has the best explanation.

[@diegodesouza302]

Love from Brazil! My name is Diego and i really love the CS Dojo lessons...even with this huge amount of knowlegment He is able to teach everything in the way We can understand!

[@xueqianchen5024]

This explanation is so good that i wanna cry...i've watched tons of videos of quicksort and still confused. But after watching the overview explanation, not even the pseudocode yet, i'm able to code it out correctly! THANK YOU!

[@mikestout6109]

I agree, This was my fifth video instructor. I got my code working during the psudocode!

[@isabelleseah8567]

Thank you for putting this series together, it's been an absolute life saver!!

[@captain-ramen]

I understood how quicksort works, but implementing it was another challenge: it was complicated and easy to make mistakes if we use the approach where the left and right pointers converge to the middle. The approach in this video is much easier to implement, but I couldn't understand it until I found this video. Thanks a lot!

[@yasaswinitirumanyam5315]

Please complete all the other datastructures, we are waiting for that

[@professorfontanez]

I compared this implementation to the one used by Gayle Laakman McDowell in her Quicksort video (by calculating the number of passes of each implementation) and found this approach to be slightly more efficient using arrays with all duplicates, some duplicates and no duplicates. Since in both cases the selection of the pivot is somewhat random, I deduced that the placement of the pivot in the middle (5:30) of the two regions contributed to this slight improvement. UPDATE: What I mean with the relocation of the pivot, is that Gayle's approach picks the middle index as the pivot before swapping values rather than setting the pivot to the middle after the swap.

[@vishalialahappan9069]

Please continue to do this great job. You are teaching so creatively. ❤️

[@alive-official7006]

I've been waiting for this new episode of your series thank so much for uploading

[@TharaMesseroux1]

Thank you CS Dojo! Very well explained!

[@arjunthecoder]

CS Dojo, the visuals in this video are great!

[@Smilista]

You explain the complex problem in the simplest way possible 🙏✨

[@coderslab645]

Thank you so much for your hard work!!!! Your vids are so helpful, and helped me understand better than most other people have. Also, i watched most of your videos and i wanted to say i really appreciate your sense of humour and the jokes, they make you even more enjoyable to learn from :)

[@warnercooler4488]

Thank you so much for the most complete and well presented explanation I have come across so far!

[@mayureshmalekar4817]

Yesterday Only (After Watching Big O Notation) I was going to comment and ask you to resume DS&A...Thanx man for this...and Plz Never Stop this DS&A series...I love the way you explain things 💓

Thank you for this update .... I was looking forward for this.. keep inspiring

[@t.k.-s.4212]

Glad to have you back. Hope you're doing well!

[@jameschen7129]

Such a great video. Finally, I understand why the time complexity of quick sort is O(n log(n)).

[@emayanvadivel6864]

Awesome keep going with more data structures and algorithms tutorials...eagerly waiting for future upcoming videos

[@coding_tips888]

Thank you please continue this series. Your explanations are very good.

Very good quicksort explanation, keep up the good work!

[@ignatusanim9644]

That's really amazing. I love it. Watching from Ghana🇬🇭

[@annali9577]

such great job, your video is strongly recommended by our lecturer. And for the buddies who still don't get head around it, I would say go grab a pen and a paper, write it down and it becomes so much clearer.

[@roman_mf]

Man, your channel is a treasure!

[@vidathgunathilake6876]

I'm so grateful for these videos, thank you mate! God bless you!

[@altash9324]

A good topic for a vlog could be how to create a real-time notification system. Which language and database is the best for this purpose. Another idea could be an example of your assignments at your work place. Also thank you for you vides, I have been watching them from the beginning of your channel.

[@Fulakitele]

This is perfect brother. I don't have any money but I will support as soon as I can. Thank you very much @CS Dojo

Brilliant, I'll check my comment again after I watched and implemented all your videos and even when I'm a good programmer.

Great explanation. Thanks man.

[@notionassistant1198]

Having a structuring system is the first step in getting organized . Then use some tools like #NOTION . Them improve your system as you go... . Nothing is perfect but we get gradual improvements on our way to EXCELLENCE! Thanks for explaining this in a way everyone can understand!

Yea, everyone should have the basics of coding to become a productive person [IMHO]
