Learn Quick Sort in 13 minutes ⚡

[@BroCodez]

This was the most difficult video I've ever made It almost convinced me to quit coding tutorials 😩 You should give it a like, it would motivate me 👍 public class Main{ public static void main(String args[]) { // quick sort = moves smaller elements to left of a pivot. // recursively divide array in 2 partitions // run-time complexity = Best case O(n log(n)) // Average case O(n log(n)) // Worst case O(n^2) if already sorted // space complexity = O(log(n)) due to recursion int[] array = {8, 2, 5, 3, 9, 4, 7, 6, 1}; quickSort(array, 0, array.length - 1); for(int i : array){ System.out.print(i + " "); } } private static void quickSort(int[] array, int start, int end) { if(end

[@irfanhakim4617]

the fact that you just handle a new programmer/coder generation by yourself is really crazyy bro

[@jaylordjl6337]

Whoaaa how did ya do that simply :( ☺️

[@Nejad7]

Quit coding tutorials! No that was one of the best technics you ever did. That effort brought this masterpiece, thank you.

[@SLIME-gx6fo]

Teach about ai

[@westmakaveli4003]

If only I could smash that like bottom more than once. You really deserve the " likes " bro. Thank you for your help bro.

[@derfwerd]

I quit my job as a data analyst at a big company to become a SWE. Your videos went from being a supplement to another resource to the main resource I lean on in many cases. When I crush my technical interview some time next year, I will let you know. Thanks bro. You are great at what you do and deserve all the success that comes to you.

[@duonghuong5738]

Hello? I have same plan as you, would be great if we can share strategy to learn in this path

[@saadshakeel6045]

It has been 1 year..! Waiting for the news haha

[@ogs3721]

It doesn’t matter if you have crushed or not, but you tried. That’s what matters the most. If you haven’t yet, let’s try together.

[@xTriplexS]

How did it go?

[@a.m.4154]

Guess it didn't go well.

[@hollowkaze8728]

just finished ur entire java playlist and now the data structures playlist, this channel has really kept me busy this past summer and has really helped me out, never stop doing what ur doing!!

[@seanfischler1320]

dawg your visual representations are absolutely saving me rn, love you

[@patrickmayer9218]

*i starts at -1 index, j starts at 0 index *if array[j] >= array[pivot], increment j *if array[j] < pivot, increment i and swap array[i] and array[j], then increment j *once j reaches the pivot, increment i, and swap array[i] and array[pivot] Thanks so much for making this, Bro Code, I am not exaggerating when I say this is the only video on the subject that made sense to me (without leaving out crucial details)! Your videos have helped the programming community so much!

[@sahu_SuMiT]

really unbelievable to have u who can put all those recursive and iteration into a movie like animation... just sitback, relax and enjoy what happens .........Awesome, truly awesome.....❤

[@bryanlee5522]

4 minutes in, and I totally understand it now. Good job. Showing what happens each step helped. This is better than the other video I watched "explain in 4 minutes". Left my clueless. And with your video, I get it immediately.

[@tubeyoueh]

Something about quicksort was just not clicking with me before I found this video. I've never gone from being so confused by a concept to understanding it so well in such a short amount of time. I never comment on youtube videos but this absolutely deserved some praise. Well done and thank you!

[@austinolmsted9432]

I am absolutely baffled how high quality your videos are. You make everything so easy and fun to understand and learn. Keep up the good work!

[@HatzzRotmg]

I have been trying to understand quicksort by so many different teachers, videos, and forums and this video finally made me understand it. Thank You!

[@irrationallymadphysicist6945]

Thanks for the concise and clear explanation! Animation can be a pain but know that your hard work is definitely being appreciated

[@reemoment1319]

This dude deserve 10 million subs

[@sumansamanta330]

Bro! Hats off to you man 😍 Completed the whole playlist 😎 All the basics are now fully cleared! Those real-life examples of stacks, queues, and LinkedList were awesome and all the shorting algorithms are now crystal clear. More power to you man.✌️🙏🙏

[@tmphu]

I never found a document or video explaining the Quick Sort algorithm this easy until I came to your channel. Hey bro, you're the best professor in the internet, ever!

[@princessattitude]

your visualization is a life-saver

[@batsy7284]

The best explanation of the topic on youtube BY FAR. Dude, thank you so much, never quit doing tutorials, you're the best.

[@dragon37786]

Finally, video without skipping recursive parts where are only two elements, now everything is much more clear, thank you.

[@_R1CK_69]

the visualization is crazy bruh this helped me understand way better than just talking into the mic thanks so much for this ❤

[@pranavkumar2030]

Such a good explainer and gem of youtube. I will constantly support your videos bro! Kudos for all your efforts.

[@hawns3212]

Fun fact, you can swap 2 numbers without a temp variable by doing the following int a = 5; int b = 10; a = a + b; // 15 b = a - b; // 15 - 10 = 5 a = a - b; // 15 - 5 = 10 Not really useful, but a funny tip to know

[@vanijatkosolomichev9452]

ha-ha, so cool :) Thanks!

[@jamesmulloy9870]

You can also use XOR

[@sao5060]

@@jamesmulloy9870 how lol

[@pothikernotes]

and in python, its just a,b = b,a

[@ignaziocrocchiolo3578]

​​@@sao5060 a = a ^ b b = b ^ a a = a ^ b (This is the xor operator ^) Or more briefly a ^= b b ^= a a ^= b

[@SamipKC-zm3gq]

I have never seen someone explain and code so easily....this was the best! you are the best!

[@domss3931]

You won the quicksort explanation game my dude, well done. I finally got it, THANK YOU 👏

[@dineshkumare1750]

I understood these concepts better from this channel than I did in my 5-month DSA semester paper.

[@salatyell]

I don't usually comment on videos, but I couldn't help myself from taking my hat off to you. I'm currently reading an amazing book "Grokking algorithms", and I Just got to the part about quick Sorting, and while he explained it amazingly and I could understand the concept of it and even visualize it, he uses python on his exemples in the book, so it was extremely hard for me to come up with an implementation of the function in java, since here you can't just add and remove elements from and array like in python... So I was looking for videos that explained neatly the implementation of quick sorting in java I couldn't find any that really helped me, but then I remembered THE LEGENDARY BRO CODE! And it just clicked! Thank you so much man! My first pieces of basic programming information came from you and I am very thankful because of how concise your code is... The way you pay attention to the convention and the way you write your code elegantly in a way that is easy to read and understand... I try to implement that when I'm writing code and all thanks to you! Keep up the good work, bro!

[@Sub-zero1123]

I was just checking quick sort on KZbin yesterday, glad you uploaded it

[@2T1R3D]

This is probably the easiest way anyone has explained any algorithm to me to this day!! Thanks, bro!!

[@dolamuoludare4383]

Finally, I met my bus stop of understanding this concept. Thank you!. This was most definitely helpful.

[@Nik-rh3xl]

This is the best video i have seen so far. Straight to the point. Very helpful, Keep up the hard work

[@DetCoAnimeFan]

Yes finally, I learnt this algorithm. A big thanks for this short and concise tutorial

[@4EverH0me]

This is my first comment ever and I really wanted to THANK YOU a lot. You are a great teacher. I am really appreciating your work. Thank you.

[@abhishekdev5251]

I never understood Quicksort this easily until today. Exactly what I needed!

[@jammandu]

Love this channel growing!

[@jp-hh9xq]

Yeah, Bravo!! I have watched a dozen videos on QuickSort. I use it every day as a developer, but this video is the best to explain it to yourself or others, in why you made a particular design decision or not. I pick my partitions carefully, and for just the reasons stated in this video. This video helps me to explain to others why I made the decisions I did!!! Thanks!

[@jp-hh9xq]

After reading your comment above, I just want to say, seriously, dozens of videos, I watched on the topic and this is by FARRRRRRRRRRRR the BEST! This is what people want to see, they just don't know it yet. Keep up the good work!!!!!

[@aymaneeljahrani2280]

The visuals made me understand everything so quickly. Thanks for the quality

[@Chris-cc6jq]

ive used all of you example videos to finally understand what a learned in another that class. Thank you!!

[@saadkhan-ku8bl]

Finally some quality content, easy to understand, Thanks!

[@mangomango5660]

Man you are a legendary giga chad coder your explanation is so good

[@sapokee2830]

Thanks so much. This algorithm has been the bane of my existence for way too long, and I finally get it now.

[@jeffisded1222]

The way you implemented quicksort is much better than the other method I found. The other method has this stupid edge-case I can't wrap my head around. Thanks :)

[@aliyanshaikh1547]

Finally someone who explains quicksort nicely. Thanks so much bro

[@boing120]

You're the best bro. The writing code with narration section is insanely helpful

[@Anas-qh3hk]

I've never been this grateful to anyone before

[@yagan_dawn2008]

I had a task to implement the quicksort algorithm in assembly.This video helped me a lot to write the code as i could easily reference my results to yours.Thank you!(It took me around 6 hours of coding to do that lol)

[@lukju6520]

This channel provides so much free information. It's just too good to be true.

[@FlameShow]

bro, idk how, but you made a real good visualusation for quicksort, it really goes easy with you, it's not the first time when you helping me or other folks, ty bro, we appreciate you, such a legend🙏🙏

[@giaminhpham2281]

This is the first time I understand quicksort, thank you

[@ManlyMango]

Wow really good job! I love the visualization you did and appreciate that you finished out the array to firmly sitck the lesson in mind. Thank you!

Absolutely BEST CASE explanation

[@lukhanyokalashe1906]

Bro given this is a difficult topic, i now undersatnd it very well and i couldnt wrap me heard around the recurvive call and how the array is partitioned only, seeing the method signature and how you well explain this. Thank you so much never stop helping us younger generation. Thank God to your C# TUTORIALS i passed my firtst year 2023 and now im able to understand data structures and algorithms in Java. Thank you Man may God Bless you. Your Fellow Bro from SOUTH AFRICA🤗❤za
