[@alexanderpetranov]

Thank you again Kunal! I went from being scared of recursion last week to being able to implement a recursive insert node in a BST function BY MYSELF thanks to you!

[@Gaurav_63]

so some little corrections that i found were : 1. At 53:20 approx in this tree you took 3 leaf node and 4 internal whereas it was opposite 2. if no of leaf nodes are 'n' then the min height has to be log(n) 3. if 'n' nodes in total min possible height = log(n+1)-1 [not log(n+1)

[@abhay80324]

yes sir right

[@workHolic-ne6eo]

also he said root node is not internal node. which is false

[@BhaweshPandey-u9w]

@@workHolic-ne6eo No, root node is not an internal node.Tthe root node is a special case of a node that does not have a parent, and it is not classified as an internal node.

[@SujeethVarma]

@@BhaweshPandey-u9w The Formula ( no.of leaf nodes = 1 + no.of internal nodes with 2 childs) holds true only if we consider root node as an internal node..... at 55:00 kunal took leaf nodes = 4 but it's actually 5

[@vedantzope8461]

for pt. 2 and 3 , I think Kunal is considering root node also as a level 1

"Kunal Kushwaha's teaching style is both engaging and effective, making the learning experience enjoyable for students. The way he explains concepts related to binary tree and binary search trees is clear and concise, fostering a deep understanding of the topic. His commitment to quality education is truly commendable. I appreciate the effort and passion he brings to the teaching process, making it a valuable experience for anyone looking to grasp the intricacies of binary search trees.

Hey Kunal, I've been following KZbin tutorials to learn DSA for quite some time now, and after wandering from one KZbinr to another I had to come back to your videos as the pattern you follow of Theory + Questions is unique in itself and very addictive, since your teaching style is so good. Thanks for the course and keep the videos coming, godspeed to my guy, I know you are gonna make it big, bigger, biggest, so all the best to you for that!

Thank You Kunal bro was waiting for this as i started dsa 2 months before i was about to complete linkedlist video and was worried where to watch the remaining concepts, thank you somuch again as you continued the course so i could continue my learning. Your DSA videos are the best and easy to understand than my college dsa lectures. and not only that you also shared about the thought process while solving the problems which helped me a lot to solve new problems easily. I already have shared with my college friends about the DSA playlist .Once again Thank You somuch bro🙏🙏🙏🙏. Hoping that i will crack faang companies during placements.✌✌

[@manishapalsam1304]

Hello are u a student?

[@gairick9]

51:26 there are actually 4 leaf nodes right? the left most node? in that case the formula holds true. leaf nodes = internal nodes + 1 4 (leaf nodes) = 3(internal nodes) + 1; inserting a node 4 - 1 + 2(new leaves) = 3 + 1(old leaf now internal) => 5 = 4 + 1

[@PrasadRanjane-rl9zx]

This bootcamp is amazing, I've learned so many new topics in DSA and my logic building have improved so much since I started watching your videos. I am very eager to learn more from these videos, data structures like graphs and new concepts like Dynamic Programming. Waiting for videos on these topics!! Thank you so much Kunal for doing this!

[@zindafossil3835]

2:10:05 I think we don't need to check whether the left subtree or right subtree is balanced or not because we are maintaining the height of every node while insertion , hence those function calls will be redundant ( if it's wrong please correct me 🙂 ) ( I am able to write this because of Kunal's great explanation ) thanks to Kunal ❤

Yes I was also thinking what is need of checking subtrees when we are finding if tree is balanced or not at root.left and root.right.
