You might have heard it many times, but still I prefer mentioning it that all these efforts you made to make such valuable contents free of cost is amazing, This is going to serve many programmers for the next coming years as well. Be it your way of explanation, your intuition every thing is just perfect. And we the programming community is thankful to you sir. I do hope that you will be making more videos in the coming years. That is the only negative thing that I hear about this otherwise wonderful channel it that the advanced data structures and algorithms are not being covered. This is just a feedback from someone who has been following your videos for quiet a long time. Again thank you sir
@@abdul_bari You made the most clear explanation on where the KMP algorithm comes from, instead of just showing us how to compute the KMP array using the pattern string. The way you teach allows students to understand the background, thus we can always recall the algorithm even if we forget. This is the same idea on learning math. You are a great teacher! :)
This algorithm is mostly used in research field. Interviewers won't expect you to formulate KMP in a span of an hour. Rabin-Karp with rolling hash function is some want less complex and less efficient algo(Better than naive though) which can be used in an interview. That being said, I'm only here for this legend's explanation, I'm a big fan from Chennai, sir.
Before playing this video, I watched the explanation by some other expressive TH-camrs, But honestly, no one is nearer to the way you explained the thought process of the KMP algorithm. Thank you for your lucid explanation.
Thanks for the explanations. If possible please correct in the video as well this: "In P3, b is also matching , lps should be 0 1 0 0 1 0 1 2 3 0", when I first saw the mistake in the video I gave up and I thought I did not understood and I searched another source to understand the algorithm. Please put a text over the video with correct values, others will miss the description and will get confused.
I have seen some videos trying hard to understand kmp, but none of them have given such clarity like u did. Thank you so much 😊. It's a wonder how just a change of few words can make a huge difference in understanding.
Used to watch your videos in my second year, watching again for revision in my final year preparing for placements! ( currently holding two offers from big tech companies)Thanks sir.
I can't say how much thankful I am. I have read this from book 4 times and still didn't understand a bit, but after watching your video only once fully understand KMP. Thank you so much Abdul sir.
I must say that u are an amazing teacher. In most of the videos, people often suggest tricks, but you explain that trick technically which sounds much more professional. Your videos are great. Please upload illustration of Red-Black Tree.
hello Sir, I know I might be mistaken but at 11:25 aren't we supposed to put 3 under be at aab since it matches the prefix sequence aab. Please let me know. Thank you for your concern. And overall I understood the whole thing. Your lectures are the best.
Teachers are God and you are one of them...THANKYOU SO SO SO MUCH SIR. Today, our teacher taught the algo but in a complex way, and said that it will take 2-3 hrs honestly to understand but you saved my time.
Thank you soo much sir for the help i was stuck on this algo for the entire day trying to watch different videos to get a proper explaination and then your video poped up and changed everything :)
Dude I love the video so much. When you found that last match it gave me a big smile. This algorithm is cool! You do such a great job explaining the concept. Thank you for the video.
Funny how my lecturer took 5 hours to teach this topic, and I actually understood during first 30 mins, then he confused me after an hour, I understood again, then he confused me again and pattern repeated, after 5 hours I questioned everything I learnt lol. And this guy did it. the right way
This is the best explanation I have ever seen. I have searched for several videos, most of them just focus on implementing without much reasoning. However, after watching this video, I fully understood the principle behind KMP and implemented the algorithm by myself. Thank you very much.
Currently I am a final year IT student and I don't know why utube hasn't recommended his video 😭 well this is my first time I am watching his video.. your teaching is awesome 🙇 thank you for making this concept easy for us
~ 3 hours of struggling with different textual posts and videos , It seems this last 20 minutes video has transitioned me from naive to KMP string search implementer. Thanks Sir

@@abdul_bari that is not helpful. what would be helpful would be for you to insert an annotation at that point in the video.
C is also matched in P3 so it will be 1234
Mr Bari, you're truly a gem. None of the videos online could explain these concepts as clearly as you. Really appreciate what you are doing!
correction: 11:27 last `b` should be 3. thanks Abdul, I find your explanations more than helpful! keep up the good work!

Its 2021 and its still the best KMP explanation available on TH-cam.
As always my professor out here dropping gems on us humble students. Much love. We appreciate you
Students are benifiting from your videos years after years... Dill se Bohot bada Thank you aapko Bari sir.. Absolute legend 🙏🏻
No one can teach better than You sir. I convey my all respect to you. Desire to meet you personally and just want to bow before you to pay my respect.

We are very grateful to you that we got such a important person in our life....
wish all these great tutorials were available when I was doing my graduation.
You are awesome. None of the people in my university was able to simplify this algorithm for me.
After searching on internet not found anything better than this video, really appreciate!! Thanks for such simple explanation of this algo.
those who have exams in coming hours start at 7.40
Thank you sir
If I passed my exam tomorrow, you will be one of the reasons

I've been roaming around tons of yt channels but I found the easiest and most understandable explanation here.
KMP starts at 7:40. You're welcome.
Of course sir, but when just one hour is left for the exam, we need your algorithm faster!! :)
AJ you are right bro , jo pura saal nahi kiya wo end me youtube se sikhte he aapn log

thanks bro
Before 7:40.... There is Naive string match algorithm...
Great ! You are a great Teacher. Thanks for saving my Design and analysis of Algorithm Paper. God in disguise.

The best tutorial on KMP. some unpeople taking money for unteaching at unacademy. And this guy is teaching and taking unmoney.
this guy is legend... i now understand how KMP works. Thank you so much.
Thank you so much sir! The book I am using has an explanation that I cannot grasp so easily but your explanation is crystal clear.
TRUE :)
You keep students interest in topic through out the video, thanks for your efforts🚀✔🤘
Dozens of videos trying to understand how the pattern works, found your video and understood in 2 minutes, tysm
I am a beginner and it was beautifully explained. The only KMP video I understood.
Thanks a lot sir!!!
I was so confused, turns out it is pretty easy! Thank you!!
Very professional explanation. No matter what, professors are professors. They know how to explain clearly :) Thank you for your time. Appreciate it.
I've been watching your video since the dawn of my CS study!!! Thank you!!!!
11:29 - the moment you realise you made a mistake but still decide to ignore thinking " chal yaar chod ... Kya fark paindaa hai"
last b should get 3 ,right?

Hi, great video. I have a doubt. For pattern P3, why aab is not 1,2,3 because it's getting repeated?
same confusion
THat seems to me as a mistake
Was still lost after a blog and 2 other videos, only your video explained this so clearly! Thank you!!
for some time i thought i was in classroom, Thank you so much sir.....
A very lucid explanation to a complex algorithm. Thank you very much sir.
in P3 for a a b repeating for 2nd time it should have 1 2 3 but you gave 1 2 0 sir..please verify it!!
awesome content ❤️❤️
I have the same doubt!
Your explanations are very clear and easy to understand
You are the epitome of awesomeness, when it comes to lucid explanations !
Sir, you should definitely create a bootcamp course for technical interviews, you ll save so many lives. Thank you for all your efforts sir !
Fabulous! Excellent explanation. Thank you sir!
I use to bunk classes bcz I believe in this man,every complex concept is easy here
i actually love you from the bottom of my heart
awww
i really wish if you were a professor in my NIT college. :)
bro u lucky to be in NIT, how are the prof there? Here its too bad, even though ours is a Govt univ :(
He was just kidding
KMP starts at 7:42
Thank you! I finally understand what KMP is talking about!
Amazing and you nail it perfectly , CS students love you
You are awesome! Can you do video of Amortized analysis and loop invariant next time? I feel like these 2 topics are hard to understand
sir we absolutely love your videos, if you could pls include the algorithms for all these concepts too!
huge respect to u sir.......every department will have one professor like this.....unfortunately i landed up here for having the worst ada teacher
Damn this the clearest explanation i’ve seen so far, not even chatGPT can explain it this clearly
Sir at 11:55 at p3 I think there's a mistake rest is great ❤️
7:40 for those who want to go straight to KMP explanation without that naive one
Again - Abdul - thank you for another great video. You make things so easy to understand without fluff.
Currently I am a final year IT student and I don't know why utube hasn't recommended his video 😭 well this is my first time I am watching his video.. your teaching is awesome 🙇 thank you for making this concept easy for us
11:37 in p3:last b should be 3 why 0?
Yes
HAIN??? KYA BAAT KAR RA HAI??
IN P3 aab and aab are same so, the next aab must be 123, time 11:55
Yes..same doubt ..it must be 123..🤔
Thank you sir. Beda garg hora tha ab beda paar hojayega 😊
