Thank you so much for all the great work you've done. I've learned a lot from you, and this is the third time I've revisited the entire playlist. I keep coming back to it every year. In this video, you briefly mentioned Red-Black Trees, and I couldn’t find any other lectures that explain the topic as clearly as you do. I would be very grateful if you could add a Red-Black Tree lesson to your playlist. Also, with your teaching style, I believe that creating a full course covering all the topics from the CLRS book as a paid course would be beneficial for all of us.

Dear Sir Abdul, I thank you so much for taking out some free time out of your busy schedule to make such educational videos.I have gone through some of the videos in your channel like BST,DFS,BFS.AVL TREE,B-TREE and found that you have explained with great simplicity but in detail keeping in mind that whoever come across these videos would easily be able to grasp the idea about the things being taught.I am preparing for my test tonight and after watching and also practising from your videos, I could easily understand things within no time.Thank you so much Sir for such a great help.You are a great teacher and you'll be always.
I am doing the same thing today. I wish my course had just posted these videos instead of what they used. Watching these, especially AVL, I can understand right away. Abdul Bari THANK YOU SO MUCH!!!!
Dear Sir Abdul, Before this lecture of yours, i never thought that creating an AVL Tree would be this much fun! It's like we are solving a puzzle. The way you're talking slowly just for us to understand, and focusing and repeating some important factors, along with giving so many examples really made me understand this data structure. I have to say, you are way better than my professor! Thank you very much for your hard work! :)
Software developer working on core C, Former Cisco employee before and now with Juniper Networks. Abdul sir's videos helped me during my interview preparations. AVL tree question came in one of the rounds, was able to explain because of these videos. These videos are not only helping students, but experienced developers as well. I am from tier 3 college and these videos are giving thousands of engineers to compete with those who had graduated from premium colleges. Thank You sir
You have no idea how much this tutorial has helped learn the concept. After all these years you are still making a difference for so many students with your explanation of topics. Thank you.
Finally a video with complete explanation of avl tree with all possible cases. Also your voice is clear and soothing to ears :) Much appreciate the efforts you put in for making such high quality video(s). Thank you.
My man concisely illustrates the concepts that my professors fail to teach me in 3 hours of talking, in just 40 minutes. Absolutely love the content, and plz keep up the good work! 👏
No words left to thank you. I was to conduct a data structure class in my company and I tried to find the best examples which I could give for an AVL tree rotation. I think this one is the best. Great teaching skills..
Fantastic work. What fascinated me was especially this example with AVT formed with set {30,20,10} in different orders. This "pullingrope " while rotations was so good.. Thank you for doing this.
I’ve almost given up on this topic. But then i decided to give this one another shot. So I searched it on youtube and i saw this video and since I’ve had one hell of an experience with your videos, i decided to watch this and now this AVL thing is a piece of cake for me. Thanks for teaching all the students around the globe. You are truly a gifted teacher
As of today I have 8 years of professional software exp. I come back to these videos time and again. But wish my college professors had taught me ds like this. I mugged up lr ll rl rr roations that time. Later on I watched/read from many places, but this content is excellent. Nothing is close to the way this guy teaches. Keep it up! I usually rarely subscribe. I believe the only way we can show our gratitude is to like and subscribe. Which unlike other you tubers this guy never asks for.
roaming.... studying...here& there.... purchasing udemy courses... not satisfied ,in the youtube ocean i got a pearl (from your teaching) thank you so much for your effort and hard work to give us clarity .you are master of algos.

Clear and Crisp. As someone coming from electronics background and working as developer and plans for coding interviews, i was looking for some channel where things start from basics , that i missed in engineering .This is absolutely clear cut explanation. Need to go through all your videos. And thanks for teaching in English ,not Hindi :-)
I watch lots of movies, tv shows and football matches all day long . Neither any actors/singers nor any players could make me their fan in my entire life. But sir ,you made me a fan of your teaching. I salute you sir .Love and respect from the core of my heart .
I was searching for a goof AVL tree explanation from last three days. You came to rescue. Thanks a lot. Very much good explanation. Once can easily implement in any language after understanding the concept.
We should appreciate teachers such as Abdul Bari Sir on udemy and coursera platforms I think the world should know that we also have genius like sir... Why should we buy courses of foreigners when we have such Indians...
Abdul Bari is a world professor and a treasure. No need to discriminate between foreign professor and Indian. Knowledge is fire and it is same everywhere. We should appreciate it regardless of from whom it comes from. I speak this as a fellow Indian.
I just wanted to say thank you Mr. Abdul Bari. I have always understood how to do RL and LR rotations but could never visualize the rotation, especially with other child nodes at play. Understanding that I can short circuit the rotations by only focusing on the first two rotations versus shuffling all things around is a life saver and now I understand visually what I am doing. I think the key for me is that you are only ever working on three nodes at a time when doing the rotation and not the entire sub tree helps focus.
Watching first seconds of this video: "Oh no, Indian accent again, but let's give it a try". 40min later: "Hey, this was actually really great!" Nice video, thanks man!
When an Indian is making a video in English, going by the common sense, one should know that it's not his/her mother tongue or even the language he uses often. Thats the extra thing he/she learned in his/her life other than whatever just the subject knowledge! And yes he's doing a favor with extra efforts there, so that most (max) people can get the benefit of his course! So whenever you come across an Indian speaking English you should be thankful let alone complain about his/her accent!!
Idk a single thing in this and i saw this video right before my exam (in the morning) and well results came and i got a full solid mark for this … thanks a lot

Wow! Amazing teaching, something I haven’t experienced at my university. You explain concepts so clearly and I love that you use analogies to explain difficult concepts. Keep up the great work!!! 😊
I wish you would have been my professor. My professor explained this to us over 2 class periods each being 1hr 45mins long and I still didn't understand it and you were able to make me understand in only 43 mins. Thank you so much.
