Following this great man from Morocco.. i do believe that india has legends and great teachers .. Respects Sir

paying so much money for a piece of paper when I end up just learning everything online. Well done sir, you are great at presenting new information to people. Definitely better than my professor, whose job is to present new information to people.

I had the pleasure of learning from Abdul Bari sir on DSA in a classroom for GATE coaching. I remember he politely asked everyone to subscribe to his KZfaq channel back then and I came home and first thing I did was subscribe to his channel when he had 400 subscribers. Super proud to see him verified on YT! this is what perseverance and hard work is really about! all the best sir!

Watching this video from Mars , Believe me No one teaches DSA better than him here .. Thanks for helping me find shortest path to moon..

This is what I call a contribution to society. Thank you, sir, your lectures have helped me lot in understanding DSA.

Sir my lecturer (He is the hod of our department) is seeing your videos and teaching us in the class 😂.. that shows how good a teacher you are!

Thank you so much Sir, Tomorrow I have my exam and I am feeling relaxed after watching your videos. Thanks again May God bless you and your family.

Bought his C++ course ! It's one of the most detailed course I have been through... Abdul sir is a legend :) Hopefully get 1M soon... Respect .

Let me be the first to say I find lighting in this video impressive. Nothing is too dark or too exposed and no shadows. Thank you, sir.

I started loving data structure and algorithm once I started watching your KZfaq video's....may God bless you..we need more teachers like you sir..

I remember watching these videos during my algorithms module exam. Now I am workig as a software engineer. Thanks sir, respect!

One thing I noticed Has he ever asked for like and subscribe Amazing

aapki wajah se humne class me padhna chhod rkha hai . Coz we know Abdul Bari ji hain naa ...So Chilll

Kabhi kabhi lagta hai ......Aap hi bhagwan hai (Specially Exam time me) Sound Knowledge with Clear explanation You have got it within you sir Take it forward

This guy's lectures' Big O of N is 1. No bs, straightforward teaching, effective explanations, just a perfect algo course existing online!

I appreciate your calm and relaxed tone when delivering information in a concise manner. Your approach doesn't seem hurried and is extremely soothing, which I believe even students with tight assignment deadlines would find calming as they read through.

You are very knowledgeable, but you are also able to explain difficult topics very easily. Thank you!

This is just for my reference sorry i don't know a better way: 4:36 start of the example 5:13 repeating steps start 5:28 performing relaxation 6:11 next vertex (3) selected 6:51 vertex 4 selected 7:18 making chart of shortest distances 7:48 time complexity of the algorithm 9:26 text book example begins 13:34 drawback of the algorithm

I don't know why I am paying more than 100 grands for a sheet of paper when I can really study and understand everything from this channel. By far the best teacher and channel for CS students out there. Kudos.

Graduating from the university of Jenny lectures, Abdul Bari, Gate Smashers, Code with Harry, Code Beauty. 🙃

You are much better than my teachers sir , you explain really well !! Thanks.

I spent 18 good minutes of life here..Thanks sir

Watched all his videos on Data Structures in C++ and really wanted to say what an amazing teacher. No one could have explained it better than him. Thank you.

Yours is the first channel where I like the video before watching it That's faith ❤️ Perhaps one day we shall have gurus like you in regular schools/colleges...

The most soothing voice of a teacher I've ever heard!

I love your teaching,sir. Keep it up. Likes from Kenya

Your relaxed approach at explaining algorithms at work is super unique and helpful! Most people teaching algorithms descend too much into theory before diving into the actual computation. Explaining the algorithm line by line, at a slow pace. Thank you Abdul!

Even after 5 years, cannot find a better video/teacher better than you. Thank you.

Best teacher so far found for Analysis of algorithm ,Sir you are Much far better than Our college teacher for which we engineering student pay more than 1lakh per year which I think goes waste on those college professors , Thanks a lot Sir for Your Efforts on sharing such incredible knowledge!

I have my exams tomorrow and i didnt even know what an algorithm is, I just stumbled upon your channel and watched a number of videos and I know for a fact that I will pass tomorrow with flying colors. Thank you Bari sir, countless of best wishes to you. You are really doing a noble job. THANK YOU!!!

Legendary explanation! You sir are giving so called expert books a run for their money! I've read 2 books & other online resources on Dijkstra, yet their explanations were so convoluted. They may had nice examples but explanations were lacking. But this, oh my God. I've watched your video, then implemented your explanation in a piece of paper, I understood the steps immediately and I was able to easily translate this into code. Based on your steps I can, not only find the distance shortest between (u,v) nodes, but can evolve it also to include the path with a simple modification. All the above, including the video, took me less than 1h. I repeat, less than 1h to fully understand + implement the algorithm, in which I spend more time reading in books & online resources. Perfect explanation, perfect teacher, you have my deepest respect sir!

We pay so much to get our degree and honestly you are better than any professor I have had. Thank you for contributing to society and makin our lives easier.

Normally this algorithm looks difficult by the name itself .But you explained it in very simple and efficient way. Thanks a lot sir!!

Mr. @Abdul Bari, thank you so much for your lucid explanation, I've enjoyed it very much. One quick suggestion regarding runtime complexity analysis: since in actual implementation of Dijkstra algorithm, priority queue data structure is used to get the next node with minimum d[v] and to update d[v], and as a result, runtime comes to big-oh of O(E*log(V)), I think it'll be nice if you could make a video specifically on priority queue and how its use in different algorithms can result in better runtime. Thanks and hope to watch a video on this topic soon :)

I'm an international CS undergrad student in Canada and I often watch your videos to study. You are doing great work, thank you from me and some other people I know who watch your videos to pass our classes!

I'm binge watching your videos for no reason and I'm learning a lot. They way you teach makes it so interesting and entertaining.

Best explanation. He sounds so much better at x1.5 :D

I teach discrete math myself, but I must say your teaching makes it so clear! I need to learn from you!

All my doubts vanished in seconds! Everyone needs a teacher like you.

PERFECT is the word. Thank you sir. I always fast forward you lectures to 1.5 speed just before interviews. :)

I didn't study for my final until the last hour because I knew Abdul Bari will teach me everything I need to know in 20 minutes.

Bari, you are one of my best teachers of all time!! thanks for giving such a lecture!! you are increasing my productivity and one more to include in your video is that, kindly tell us the practical usage of each algorithms in the real world and how they are solving it!!

You have some magic within you sir. The explanation seems so simple. I'm sure that I'm Never gonna be forgetting this concept. Thank you for the splendid explanation.

literally studied most of my finals from this man for the past 3 years of university, thank you so much I will keep you in my prayers.

I've never seen anyone teaching DS like this. You are the Best!

started studiying 12 hours before the exams ! was in panic as i didnt had any time to study for the final exam of DAA but gave these series a try and now looks like i can do something in exam ! have confidence now ! still 2 hours to go for exam ! hope it will go good thankyou Abdul sir for help !

Sir, max of the students in our class follow your explanations, even our lecturers suggest ur lectures. Long live sir. U are really a great help for many students

One of the best teachers in my life. Though he is not teaching offline but the way he explains and makes the difficult topics very easy is priceless. Thank you Sir.

thanks sir its really very helpful for us not only that lecture but all videos. thanks again

Brilliant explanation. I loved how you took only 3 vertexes first, to explain the concept

Thanks for one more great video !! Btw, This is my understanding of Time complexity: 1. *Initialization:* - Setting the initial distance to each vertex: O(V) 2. *Main Loop:* - The main loop of Dijkstra's algorithm runs for each vertex in the graph, processing each vertex once. - Within each iteration of the loop, we extract the minimum distance vertex from the priority queue, which takes O(log V) time in a binary heap. Since this operation is performed for each vertex, the total time for this step is O(V * log V). 3. *Relaxation:* - For each vertex, we iterate through its adjacent vertices and relax the distances if a shorter path is found. - In the worst case, each edge is considered once, leading to O(E) relaxation operations. - Each relaxation operation involves updating the distance of a vertex in the priority queue, which takes O(log V) time in a binary heap. - So, the total time for relaxation is O(E * log V). 4. *Total Time Complexity:* - Combining the time complexities of initialization, the main loop, and relaxation, the overall time complexity of Dijkstra's algorithm using a binary heap for the priority queue is O((V + E) * log V). In summary, using a binary heap for the priority queue in Dijkstra's algorithm results in a time complexity of O((V + E) * log V), where V is the number of vertices and E is the number of edges in the graph. PS: Thanks to ChatGPT !!

i literally didnt take one physical class properly cause my instructor was the worst, but you sir just explained my whole syllabus in a matter of minutes. mad respect sir thanks alot

never seen a better explanation than this

I love how when he turns around, his look screams - It's that fucking simple...

this video was recorded six years ago. here I am watching it and learning from it . thank you for making this video . From Seattle, WA USA .

I wish you were my algorithm analysis professor. Your explanations are clear and to the point, thank you for your videos.

Sir you are teaching like flowing water; elegant!! keep it up!!!

Sir, i have an exam after an hour, you're saving my life, remember that! you're an absolute hero! LOL

Sir your videos are a golden mine for understanding concepts of DSA. Your teaching style is one of a kind and it is extremely convincing and easy to understand Thank you so much

I wish you were my professor when I studied. The way you teach, students no need to refer any books for exams. I found your channel recently. Thanks for your time and passion teaching. God bless you!!!

thank u so much sir. u cover little things of other topics in single lecture.. really awesome...

1 like for sir in 2019! Great way of explaining.

Extremely clear and to the point videos, thanks for a such a quality content !

you're the reason I have been able to do stuff with my Data Structure class. thanks.

Wow. I can feel Abdul's passion for algorithms flowing. He is making learning so enjoyable.

Why do the Uni lecturers in Australia explain it in the most confusing way? Thank you sir you are doing great.

precise and elaborate lecture at the same time! In a word- Amazing

You teach so well. So easy to understand in comparison to so many other academics. Thank you. Very grateful

I want you to be my professor, you make all concepts so easy. Thank you so very much!

Your classes are pretty good, Mr. Bari. Greetings from Brazil.

You are the most effective teacher I have ever studied from, You make things simpler.

i was on a zoom class when my lecturer explain this, and the way my lecturer explained is a bit confusing. So thanks to you, this is much simpler. thanks.

great video , please make these implementation in programs too.

After seeing your lectures, I'm in wonderland sir😃😃. How beautifully you have explained everything 😃 Amazing work sir. We are grateful to you 🙏🙏🙏 I see God in you , sir. Lots of love❤❤❤❤

You are such a great lecturer sir ! Because of u many of the students are getting benifited ! No exam pressure for the student who were selected u as for their preparation we were so glad to have u of free of cost sir thanku sir!

HUGE THANKS FOR PUTTING IN THE EFFORT AND UPLOADING SUCH GOOD QUALITY CONTENT ON KZfaq. :) :)

I have my exam tomorrow and that was an absolute treat to watch 😃

Great job, Dr. Bari! I am a computer science student studying in the U.S. - and your videos are super helpful! Many of them explain concepts better than my professors!

I am a guy who always used to hate DSA, I also had backlogs in the same. After finding your videos Abdul Sir, I have started loving DSA. I am thinking that why didn't I know about your videos, because if I would have known, I wouldn't have had any backlogs. Thank you so much, Sir! :)

Thank you DAA turorials.I passed my exams just by watching your video :)

You were great Abdul! You explain very well. Thank you!! May God bless and protect you and your family.

Thanks very much! I like your courses being so DRY/CONDENSED!

That was a great help, I am noww able to solve related problems for my college exams. Thank you for your efforts.

This man literally got me through college he’s the best

Thank you soo much sir. It helped me a lot To understand algorithms. 🙏🙏🙏

Perfectly clear. You were able to explain me what my teacher wasn't able to do

really love your techniques and the way of teaching. this made my exams way too easier than i expected.keep teaching us you are a real prof sir. blessings from Sri Lanka

You are a born teacher sir!!!!

Sir your simplicity and tone is amazing.Big fan from West Bengal.

Sir explains the algorithm with such calmness in a short time, really a blessing for all of us that we can grasp important concepts online and a L for uni for not teaching us real education

Sir, you are the 'Algorithm Boss' in my eyes, you are my great influences, Thank you sir & also take my heartily respect to you..👏👏💗

Saying just thanks is not enough sir...stay happy and healthy.

Sir, tomorrow I'm having my end semester examination in data structures & algorithms. Your video helped me a lot sir. Thank you sir 🙏🏻🙏🏻. You are a legend sir. Please upload more videos sir🙏🏻

Sir I tried to learn concepts from many tutorial but unable to understand some concepts then I saw your channel and watched your tutorial on that topics and understand that algorithm (concept) very well. Thank you sir for explaining in such a way ❤️.

Five Year Ago The Playlist was Uploaded But still no one can compete it Thanks Alot For Such a WonderFul Playlist For Free

Trust me or not....I got an A+ at msc cs course in ds and algorithm course with your videos help. With your methods, even a 10-year-old can understand algorithms and ds. I have no words....LEGEND!..LEGEND!...LEGEND!!..You are my second favorite Indian next to Udit Naryan. : )

Your videos are having a bad influence on the students. They are skipping their classes because your methods are way better.

Abdul is the man! I go to a well known CS school, and his explanation of Dijkstra is about 1000x better than what I learned in class.

A good teacher is one who can explain a complex subject to a layman...a good teacher explains through examples...he has both the qualities...and thank you Sir for explaining the topic so clearly 🙏... finally grasped it🙏

Sir I am very proud to say that u really helped me from the backlogs 😂😂😂😂
