It has been 5 years but still these videos are better than new ones by other youtubers.....i am referring to these in 2023...thank you sir

*I am from ECE Background, trying my hard for product based companies and I want to thank Sir Abdul Bari for all the Concepts which helps me in competitive programming*

Ok i can Proudly say that He was my lecturer At College ❤️

You are the best teacher of algorithm in KZfaq

thank you for all your lectures, you are like a god sent to us.

Abdul Bari Sir I just wanted to thank you. I have successfully completed my M.Tech with good CGPA and yeah topped at college level. You contribute a lot to my grand success. Thanks a lot. But I regret for I could not find your videos during my B.Tech. Anyways, ALHAMDULILLAH. Now watching your videos to prepare for teaching demos.

That's great contribution Professor! Everything in the presentation is superb - contents - speed of delivery - board usage - selected examples Everything Hats off to you Sir 🙏

Thank you. One of the best description on Backtracking, and its difference with Dynamic Programming.

A simple way to explain the N queens problem & solution, love it! Greetings from France

i'm currently watching to save my self from failing my class thank you

Great ! You are a great Teacher. Thanks for saving my Design and analysis of Algorithm Paper. #Respect

You are so good at explaining this. Thank you so much for your time!

Thank you so much for your videos! I am trying to self-learn competitive programming and your videos are a great help to so many students around the world! Keep doing what you do best!

Your explanations are super clear. Can you add videos about topological sort, strongly connected components, and bipartite graphs?

exceptional articulation sir. I myself get's confused going through it step by step while you're able to trace it accurately for each node. Really inspiring.

Thank you Abdul Bari sir for your videos on Algorithms. They are helping a lot of students like me. Your work is very much appreciated.

This is such a wonderfully satisfying concept, and a great video, too. Always love sir's peaceful energy.

This is very good sir. I was in very confusion of brute force searching of solutions of Sudoku. But the lectures of you have cleared this. Your explanation is too good and I am really very happy after seeing your videos. Thank you sir for teaching us.

sir love your videos...kindly consider including the algorithms along with the explanation

Amazing sir. I loved your videos.. I'm watching these videos a night before exams

Very nicely explained! And not too hard English used 😋

Thank you,Sir.You made the searching problem easy to understand.

it was a great explanation, you deserve million views

Abdul bari is a awesome person..he cleared many of my concept....keep helping us Sir

Those who watch in 2024 assemble here guys 🫂😍

Everytime i used to watch your lectures but never bothered to comment...but sir you way of teaching is superb! Thank you for your lectures.

Made the problem easier well done Great privilege to see this

Thank you sir for clearly explaining step by step

thank you so much for all your videos, major help!!

After learning from your video lecture I completed certified course very easily u are great🙏

After the first arrangement of all the queens,shuffling of q3 was done and so was done for q4. As q4 was already in 4th column why you have written q3 in 4th column?

I have done crazy amount of practice finally I understand it perfectly. keep doing practice you are going to master it.

Really helping your videos alot professor.. Thank you

this guy is amazing ! teaching us with lots of care and effort.

@Abdul Bari Sir, your explanations are so amazing!!

Great Sir. Clear explanation. Thank you so much Sir.

Abdul sir, you are the best ♥

Can't be grateful enough for this Man's work , hats off.

Thank You for explaining it so well! :D

Very great explanation. Thanks sir, you earned my respect

Well Explained the Solutions .. specially that mirror image of last vedio footage 13:30 ... Thanks Sir

very good explanation. very helpful

I love ur way of teaching sir.u makes the lesson easy.Love from bangladesh.

Sir, can you please show the steps to find the time complexity using the recurrence relation T(n) = nT(n-1) + n^2

Thank you master you're the best explaning👍

Thank you sir! Really you are a great person, lots of love and respect

great video, you're a great speaker

Thank you sir .you are a great teacher.Great explanation.I am subscribed.

Thank you so much sir this concept is really easy but my sir can't explained in depth..

wow.. It's really fun. I'm not good at English but this lecture is easy to understand. I already know backgrounds, but it's very fun to me. now i'm conside buy ur other lecture.

Thank you sir for such great explanation!!

Note that the reason you're able to restrict the first queen to the first row, second queen to the second row, and so on is because they are all queens, so it doesn't matter which queen is on which row -- they will all function the same way. In other words, the ordering of the queens doesn't matter. You could just as well put queen 3 in row 4 and queen 4 in row 3 and achieve the same result. We are forcing there to be a single queen per row, since otherwise two queens would be under attack, and are just interested in specifying which _column_ the queen in each row will be on.

Brilliant explanation. Thanks, Professor Abdul!

Explanation is awesome but please add programmatic pseudo code also

Really Great Prof. Bari. very nice demonstration.

Thanks sir... U gave us THE BEST lecture

Dear Guru...! Its very great that you've explained well .but we as a learners we'd also expect it in Algorithm tracing .if you possible could you please make it out sir

Nice Explanation...Thank you sir

Amazing sir Understood in a single go

the way u are teaching is excellent sir.please continue to make videoes

Sir, you are really great. Thanks sir

Hi sir I saw the video of n queens problem ,it helped me lot to create my own presentation Now I am in need tug of war problem using backtracking

Hello sir, what book or resources did you refer for DS and Algo

wonderful teacher u r ..........sir most of the student try to study cormen book of algo but failed to do so ......sir plz make videos of cormen book explanation .........it will be of grt help to many..........thanks

What a great way of explanation. Thank you so much Sir G

Very Good Explanation. Very Helpfull

Don't know what I'd do without you!!

without your lectures we are wasted sir♥️♥️💯🔥

What do you do about the solutions that don’t have q1 in the first row? Wouldn’t that open the solution space?

You are excellent teaching in DDA subject TQ sir

Thank you very much sir I have clear this subject in just two days before exams👦

Thank you sir very nice explanation...

god aur banao aaise log duniya mai itne clear minded

Excellent sir...Thank you very much...

Sir, I suggest you to make comments about the complexity and algorithm/program for each problem, in that way it will present complete discussion about a problem otherwise students need to search other content for getting answers to these questions. Thanks!

You are an Inspiration sir✨

Great explanation.. Please could you also add the pseudo code and explain it

well explained......thank u sir jii

*3 things to worry about so queens don't attack each other: same row, same column, and same diagonal *generate a state-space tree *the default is that the nth queen is in the nth column and nth row (they form a diagonal on the board from left to right) the state-tree backtracking starts at 8:40 Thanks for the video!

superb explaination in simple words

Thank you for a great explanation in a short time.

So underrated. I'ma share.

Very good tutorial. Very systematic

For 8 queens do we have to find all the solutions or one solution is enough?

Would you please elaborate on the time and space complexity? Thanks!

Loads of respect sir and thank you very much sir

Thanku sir you are doing a great work ❤️😍💕

First year here, this was extremely helpful!

my favorite teacher on utube

Sir, can you please solve 8-queen problem? I really like your explanations 👍😊

thanks one ques that i think u have the row in which the queen 1,2 etc can be in otherwise there will be many more soln jus by onterchanging gthe pos of the queens .

what if i fixed 2 queens in 8 queen problem , then how many solutions exists in 8 queen problem?

Great explained, thank you

Thank you, great explanation!!

How can I solve 8 queen's problem the tree become very complicated... Plz sir advice me what to do...

Thank you very much sir for so easy explaination.

sir we are back benchers so sorry for this meru explain chesey way ke okkati chpali sir me modda ke salam me gudha ke gulham hattsoff sir for passing out in this subject

thank you sir i want to ask do you have any tution class inside india that you train as

Such a great way of explaining the QueensProblem ... Thanks a lot!

You are the best teacher sir
