Even in 2021 when there are so many videos/playlists available on KZread, it's hard to find this much easily understandable and quality content on DSA. 😍

@@CuriousAnonDev Unfortunately one of the two people who started this channel is no more.He died in an accident in US and the other person wasnt in right state of mind for few days.I hope they r both fine in their own worlds now ....lots of love to their work
The number of lives this channel has touched is far far greater :) Reason: In the year 2014 there were hardly any DSA channels on youtube This very channel inspired the entire generation of Data-Structures KZread Channel.
I have followed all your Data Structures videos, they are great! I love that you just dont explain the ADT but also show how to code it. That´s really helpful for somebody like me which still doesn't have lots of experience coding. Keep the good work! I'm waiting for your new videos to come out! =)
amazing how my college professors don't take the time out to explain it in depth as much as you do, truly appreciate it.

I have starting liking data structures after going through your videos.. Really appreciate !!!
After looking through so many resources, I must say that your explanation is indeed the best one on this topic. Really easy to follow and understand. Thank you !
I took the baby steps of programming (DSA) from this channel and after 7 years I am here again for my interview preparation. Only if the channel was continued we would have seen the golden content. But destiny had some other plans. :(
Out of all the search results KZread shows me when I search a specific topic I always look for mycodeschool Videos. Simply outstanding!
I cannot say enough how helpful these videos are. You are literally saving my grade, one video at a time. Thanks for being an amazing teacher, these videos are the BEST.

Really a good explanation of BST.Worth watching to this tutorial.Neatly explained.Thank you so much.
best explanation on youtube in my opinion, this helped me when I took data structures and algorithms and it helped me again when I went to tutor it a year later. Well done and thank you.
I had a hard time understanding the deletion process from BST, especially the third case, when a node we want to delete has both of its children. This video has made me understand, you explained very clearly, and I came to realize that the procedure is actually quite simple haha. Thank you very much! Your channel is my favorite when it comes to algorithm tutorials! Please keep posting more, I really enjoy them!

Same Here Right now for me.
This is the simplest and best explanation for deletion of a node in BST. Take a bow from me. Thanks for making such a nice and useful video. I am grateful to you
Woah. That's the best explanation of the delete operation I've ever read/watched. Thank you very much.
Thank you so much for making the most informational and understandable videos on BSTs. Saved my grade in data structures!
4th video I am looking at, very good and clearly explained. Thank you for your effort! Had to recapitulate for an interview, ages since I learnt it in school and had to use it.
i rarely comment on your videos animesh sir but this was Truly Exceptional explanation, nobody explained it the way you did. This is why clean code and moreover the teacher matters so much. Again thank you so much for this contribution to the society . Love and Regards to you and Late Harsha Sir
i had a lot of trouble understanding this! thank you so much! clear as hell explanation where all other lecturers failed. clear and simple and to the point! you are awesome my friend awesome!
this method is so much better than the method suggested in my "introduction to algorithms" textbook. Much easier to understand, and the code is cleaner. Great job!
I usually don't leave any comments, but this was very clear and helpful!! Thank you so much
A headache concept(for me), explained in the most simple way! Pure brilliance.
Your lectures are awesome,easy to understand and practise. Thanks for your effort.
Your videos are probably the best explanations i have ever got! Thank you so much!
I just can not switch from this page without thanking You! For having learnt from your videos. Thank You very much.
not only is this video on the topic I need to learn for my data structures class, it also is in C++ which is what we are intended to use, amazing.
this was the best explanation i could find on the internet. THANK YOU
You have a very good way of explaining stuff in your videos! Great job!
Thank you I successfully implemented this in java code. Recursion algorithms need more time to be understood but thanks to you it took only 18:26 !!
What a trick on case 3. Just wow, I was doing it the hard way. But you just made it soo simple, by continuing recursion and deleting the extra node with case 1. Mind-blowing 😄. Still Relevant even after 8 years
excellent explanation of deleting element from BST. Thanks.
thank you so much....i think this was the best video of programming language i have ever seen....keep it up...and thanks....your quality of explaining the concept is really very good...
This series is beautifully crafted. completely flawless . i would even pay to watch your videos.

It seems that u have great understanding of concepts and nice way of explaining too.Hoping to post many more concepts.
Great explanation! Thank you. By the way, I'd like to point out that this deletion algorithm is not suitable for balanced trees since it will not preserve the balance. This algorithm is called Hibbard deletion, and one company was sued in the past for implementing this algorithm as the deletion method in a Red/Black tree implementation.

This is only for binary search tree .. it won't work for AVL trees and Red Black trees
i do not think there exist any channel which is comparable to "my code school" , this guy explains the code in the most easy and logical way while others do spoon feeding .
Thank you very much for your clear and concise videos on data structures!
thank you so much, i've been struggling with understanding binary search trees so much, but your videos explain it so well! One video is worth 10 lessons at my uni lol.
Fantastic video. Your description helped me to understand tree deletion. Thanks.
I was obsessed with the tutorials of nptel.But now you guys are my brand new obsession after this video.

please upload the video of hashing,avl trees ,graphs.i have been watcing your series and it helps me alot in clearing the most difficulty parts.
Really good and easy to understand explanation of delete operation. Thank you!

Super clear explanation on BST node deletion. Thank you.
Really nice ! Its clearing my concepts !! Its simple and to the point.
amazing as usual ... you are simply AMAZING instructor thank you so much
Thank you. Excellent video .
best explaination I've found for this.
I directly started trees ds,and i really loveing it because of you buddy
all your concept explanation is awesome sir
Wow, this video is awesome! I was stuck with the delete function and couldnt figure out how to link the current ptr with its parent node :o, I did see a lot of sample codes and didnt understand how the recursion unfolds and sure enough I was missing that return statement :( I initially had my delete function to be void, now I understand what the return is for. Thank you so much, will definitely be watching more of your videos
Thank you. Literally helped comfirmed my idea of finding the max on the left side. I'll do just that now.
Very well explained! Thank you! I have a question. So since deleting max from right subtree and min from left subtree both make deletion work(for the case when a node with 2 children), which subtree do we choose?
Thanks for the video. Question on case 3, if there are two 17's on the right side, the tree would become invalid because you would have a value that is
Deletion in BST part is always tricky and hard. You explained well. Thank you
Thank you so much. The best one so far!
