14:51 is where it gets EXTREMELY confusing.
There is a little mistake in ur algo if (parents parent is root ) no recolour u missed no here pls check it and if i m wrong tell me
Amrita Dutta
Hi Tushar, Your playlist on Tree algorithms is comprehensive. Wondering if you can add a video on B-Tree.
Nishtha Jain
Good Explanation Tushar Sir. Glad to have come across your channel.
Nikhil Manali
bro hats off to u .You are the best ..

LOL!!! at 2.23 ,That 2nd tree is not a red Black tree 'cos the number of black nodes in the last sub tree is 3 not 2.
anand kumar
Nobody has elaborated and embellished RB tree with this perfection. Thanks man!!
Vlad Brincoveanu
Thank you !

Sir plz make more videos on algorithm
Madhvi Bansal
Wow . I didn't understand this topic from my teacher but listening this lecture all the cases would clear . Thnk u sir for making this video.

I have my data structures final exam tomorrow morning !

red-black tree corresponds to 2-3-4tree ,left leaning red black tree is equivalent of 2-3 tree
Anand Zutshi
Thank you so much for this video. I loved it. I have a knack for data structures; especially trees. I would love to learn more about advanced data structures, and their optimised solutions by designing new data structures. Could you please give me some advice as to where should I start in order for ds design and implementation? Are their any projects for it? Thanks in advance
Rajeev Kavish
yeah , i understand rotation pattern very well but hold on ,could you please specify 2 nodes with which rotation takes place.......

Very good explanation! Thanks.
Patrick Garcia
does a red-block tree always balance??
mita Rani
Well explained . I try read nd understand from book but it didn't help me out .. but this video makes me to understand well....
Shikha sachdeva
Thanku sir
Why are his eyes always half open?
Chitrarth Tomar
The explanation is very good. But this tree is a bit racist(pun intended).
Daljeet Singh
your videos are so clear & concise,wish you had been my data structure teacher...seriously great work man
Christopher Harsh
Thanks for this video. It was extremely clear and well illustrated.

It will be very helpful if it's bit slow
Benjamin Rood
Thanks Tushar! Very, very clear and simple explanation, when there are so many poor ones out there in textbooks or ones which just hand-wave the deletion algorithm. One small quibble: @30:59 your second bullet point could be "For all distinct paths p in our tree, the sum of black nodes in the path sequence of p from a node x to any leaf l must be identical" - but really, even in that sentence, as with the writing of your bullet point, the word should be ANY rather than ALL (knowing that the logical symbol of "for all" is also "for any"). In other words, it should be "same number of black nodes in ANY path (from a node x to some leaf l)". Super subtle, but it might be worth a subtitle on the video which clarifies it.
Goutam Kumar
Hi Tushar, just a small question, is rightRotate function , before the changeColor condition, you are checking for null case of right node, but in your code of github it will never be null instead it will be empty node with isNullLeaf = true, hence it will always assign parent. Anyways no harm in doing that, just to tell, I think its redundant
j karthik
Thank you so much for making videos on DS and Algos and making developers life simple. I use to spend more time in understanding Algos but after your watching your videos my preparation moved faster... And great explanation .....
Yashdeep Sharma
Nice explaination sir
shilpi sharma
:* thnku  so much
hi, thanks for the video. Really helpful. I did not hear you mention as CLRS that to analyze case 1, case2 or case3 during insert new node. The program on board is following that, or it is a different program or process?
Margub Khan
very nice explanation.. plz do a video for deletion....
Ritesh Singh
Great work sir
thank you so much. Really helpful and the concept is very clear now. :)
sakya basak
Thanks Tushar ........these videos are among the best that is available online...... Can you plz give a video even for tries/ sufffix tree?Thanks in advance
Sourav Mohanty
Hi Tushar! Your videos are the best. Please upload some tutorials on Maximum flow Algorithms. And keep up the awesome work you are doing. :D Thanks in advance.
Amit Sarkar
Thank you sir, its now cleared to me, this tutorial is the best

nice video , but u forgot the condition of every red black should be transformable to a 2 4 tree

Thank you ;-)
sachin tichkule
Sincere thanks for explaining the concepts clearly , but one humble request , if i am not correct please apologize , i am not able to follow ur pace , feeling it little bit faster , but if can slow ur pace of explaining little bit , it will help lot of beginners like me and help us to understand concepts clearly.
at 17:42 the color of -10 should be black
Tripti Pandey
Ur voice is not clear so please use simple English
Rajni Kant Yadav
Every leaf node is supposed to be a NULL node right? But in your examples you have random NULL leaf nodes? I didn't quite get that. Please reply...
lavanya devarasetty
It's Soo interesting the people who doesn't know abt dis topic can easily understand I m.very happy vd did lecture .and I need even for splay trees
Nulls are black :)
Sanket Neema
