I think we fall in love with educational content creators/professors like this because they take us from a place of feeling totally stupid to a place of feeling hope for our future. It's s beautiful thing
Though I was ignorant about either steps until I watched this video, I patted my back for having used DFS logic for an recursive algorithm to traverse through nested groups for an application I was working on. Kudos for such a detailed explanation and analysis.
I am an Experienced software developer with more than eleven years of experience, i have never seen such a talent you have, you explain things in best possible way. In my almost 15 years of watching online tutorials i have seen someone who explain who can explain complex problems in simplest way possible, simply you are awesome :).
This is sooooo cool! This is like hit the point DIRECTLY without any unnecessary nonsense! Just like a brave soldier hit to the emery heart quickly and sharply!
This came in my recommendation out of nowhere. I still remember watching his all videos and clearing advanced data structures in sem 6 of engineering a couple of years ago. Students, just watch his video, makes notes, and give your paper, you’ll pass smoothly
one of the best professor ever, I got an A in data structure and algorithms by just watching his videos and go stretch to exam. I don't need to look at lecture node.
There are certain things that I can barely understand when I am in class, but when I get tuned to your lecture everything seems very easy as "BONJOUR" for me. Thanks, I really appreciate your performance in explaining this course online.Wish you the best!
I usually do not comment, but this dude had explained traversals, which i was struggling to understand, in just 20 minutes. Thank you very very much!!!
This is super helpful thank you!! Just a clarification, I believe there is a mistake on 13:56. When going from 3 to 2, add 3 back to the stack so the stack should be [1,4,3]. Then at 15:25, go back to 3 and then to 4. I got stuck here a bit, so I hope this helps someone.

Hi Sir, I am from the University of Sheffield, UK and everyone here loves your videos. You are so much better than our professors. Please keep up the good work and god bless you
Hello sir, I just wanted to say thank you. For the longest of time i was very intimidated by the tree search algorithms and was putting them off. But you just make them seem so easy. Your explanation and the visualization of stack and queue while solving was a big help. Thank you so much you really helped someone today
Well structured, good pacing, clear delivery and very articulate. I can't understand how some lecturers can make a mess of such straight-forward algorithms, yet on RUclips I find 18 minute videos that can teach them perfectly.
I landed here while trying to solve CS50 tideman. I have no math/logic/algorithms background, yet I immediately understood this exploration. Thanks for the video! I'll be back to watch the entire course in the future.
this is what feels to be taught by a real teacher , earlier i was watching the tutorials of other youtubers , i agree they (youtubers) have the knowledge but having knowledge and be able to teach that knowledge in a way that is both simple and clear is a whole another thing. thank you Abdul Bari sir... i will watch all of your videos .
Such a simple concept that my professor tried to explain in such a confusing way, thanks for clearing everything up! All of your algorithm videos have been super helpful! I would love to see some coding videos in the future, maybe?
I'm so grateful for this. Love your way of explaining. BFS & DFS for graphs seemed so complicated & hard to master in class, but I understood them so well & easily just by watching this video. 6 years later & this video is still SAVING LIVES💯
Currently taking my Data Structures & Algorithms course, and whenever I don't understand a topic, I can find a video on this channel that explains it perfectly. Thank you for this channel!
@Alvin Benedict You guys could also support him on Patreon, the link is in the description. Just because he doesn't start his videos with an appeal for patreon contribution doesn't mean it should be ignored.
This is my first time watching him, and I’m also diving into the vast ocean data structures and algorithms for the first time. His explanations completely blew my mind! 🤯 I used to think that DSA was complex and beyond my reach, but after watching this video, my perspective has completely changed. I now feel inspired and empowered to tackle DSA concepts for my future interviews.
@@thebot177 today is my exam. And I started studying for semester day before yesterday. And I'm confident that I can clear my DS. (BTW, I'm Engineering student)
It all depends on the exam. At my school in Germany, the exams are always the same more or less. For most exams if you just want to pass it with an okayish grade, you just need to practice the tasks of the exam.
I am studying Artificial intelligence in university of Tasmania and the lecturer is Chinese and I cant understand his voice but you explain with your clear voice and tone which help a lot .Thank you so much.
I’m a college student from China. Your video provides me a new perspective to understand bfs & dfs using queue and stack. And I do learn a lot from it! Heartfelt thanks:)

I studied completely wrong dfs and bfs on utube from other channel and told my senior abt that she told me it's a wrong way and trust me i thought she is wrong and then i found this vdo sir u just saved me from failing tommorow , my senior was ryt ❤️
OMG... After following through the first example, i paused the video, went back to solve the initial challenge that brought me here, before coming to complete the video. Never seen complexity demystified like this.
Nice! There's just one important thing missing. When using depth first traversal you have 3 subcategories (pre-order, in-order, post-order). In pre-order. the vertex data is read first then it goes to the sub vertex. Whereas post order the vortex data is read last.
I procrastinated on implementing BFS & DFS for a long time due to lack of full understanding of the concepts behind them. After carefully watching your video I implemented BFS with performance better than 99.97% submissions on LeetCode and implemented incredibly shitty (but working!) DFS myself. Thank you for your contribution!
Every time before exam i watch only your videos which give me strength nd confidence that i can happily attempt the respective topic easily in exam 🙏😊...thanku sir!! Really tq so much✨✨
Just wanted to say than you so very much for your clear explanation of this topic. I have been so confused with my textbook but you have saved me so much frustration. Thank you, thank you!!!!
Thank you again for the lecture, this was very helpful to me watching again as I did not understand the variations in depth and breadth the first time. I am liking the binary tree example very much to show that the linear order of the nodes (their sort order) is arbitrary (no pun). There is so much content on this channel, very educational and clear. Thanks
