What is AVL tree ? 4 Basic Rotations(Left, Right, Left-Right, Right-Left) for Balancing with Diagram
HTML-код
- Опубликовано: 10 июл 2024
- AVL tree is a self-balancing Binary Search Tree (BST) where the difference between heights of left and right subtrees cannot be more than one for all nodes. This difference is called the Balance Factor.
In order to perform this balancing, we perform ROTATIONs on the unbalanced/imbalanced Binary Search Tree to make it a AVL tree.
We peform 4 basic rotations depending of 4 difference cases -
1) Left Rotation
2) Right Rotation
3) Left Right Rotation
4) Right Left Rotation

I like how you tell us to keep distractions aside and not check our phones in between like an elder brother. Thank you
you are the best in ALL RUclips you are out there saving lives, i will be forever grateful for you
The best video on BST rotations I’ve seen. Thank you
was waiting for this topic from past 20 days
keep doing, great job. Only because of you I am able to understand AVL tree
This channel deserve Million subscribers....
The best explanation I've watched! Thank you
excellent video dear friend of mine. indians are always the best explaining these sort of computer science stuff, and this one is the best video ive found of AVL rotations
one of the best explanations. thank you!
Very nice explanation 👌.Addicted to your voice and explanation.Thank you so much.
So nice of you. Thank you for the positive feedback. 😇
Such a great explanation!! Thank you
Thankyou for the series!
I really the way you teaching, such a detailed illustration:)
You have great concern about viewers..
Love you for your extraordinary content and lovely explanation
Dude you are the man, thanks !
Thank you sir .One thing, I desperately need the BFS and DFS graph video. Please!!
Waiting for this man... Plzz upload more avl videos
just one word for you-> "AMAZING"
thank you dude, better than my own proffesor
Congrats! Very good explanation
Well explained thankyou !
Thanks bro for finally starting this topic 👍👍👍
Welcome 😊
@@SimpleSnippets when will the next part of AVL tree will come , please bring before my exam Dec 22th.
Best explanatioin hope you start a lecture on DP please
bro this was an amazing explanation
Very good, thank you. :)
fully
explined
ultimate explanation bro. Keep doing ... keep going ....................
Thank you so much 😀
Helpful
Thanks
best video on youtube.
Thanku ❤️❤️❤️💐💐
Hii brother,
best explanation ever of avl tree.
I want to ask you which tool you are using to prepare these lectures. Tell me the name of it. I wanna also use it
LR rotation can be replaced using RL based which whichever number is imbalanced, 1 right rotation about n1, n1, becomes right child of n3 and n3 remains right child of n2. Then a left rotation about n2 and then n2 becomes left child of n1 and n1 becomes right child of n3.
you r the best...masum
Height of a node in a binary tree is the no. of edges from the node to the leaf node .
Huge fan sir✌
It would mean a lot if you could please share our channel and videos with your friends too ✌
Just loved your channel 😍 take love from Bangladesh ❤️
Brother when we will get graph vedio?
Thank you so much bro 😊 graphs will take some time as there's a lot to cover in trees first. Once that's done I'll take graphs too
@@SimpleSnippets ok brother i will be waiting for that & your are doing such a great work❤️keep it up😁
Bhai Thank U So Much. Bhai, also can u upload code for rotation (ASAP), because many viewers of yours (including me) are in semester system, so we are waiting for your more videos. so, it will be very comfortable for us.
I will try
thanks for sharing! do you have sample code?
Bro please make a video on trie data structure as well I am having really a hard to time to understand it. btw love your videos
Yes I've already made videos on tree DS 😊
@@SimpleSnippets Yes I know you have made that video and I have seen them all but what I meant was "trie" Data Structure like the "retrieval" the one that is used in the application of finding a word in a dictionary. Thanks for consideration!
25:01 arrows direction is not correct for right rotation is it?. Great tutorial BTW.
++;
Can you also make an video on N-ray trees?
Can you please share the tools used to mark and highlight while you are explaining the video.
applications and devices used to draw effectively
no
sir your video is so help full for me thank
but request you cover DP, Graph, Greedy ,Hash Divide and conquer Please
can we say that for a particular set of nodes AVL tree is unique?
also nice explanation thank you...I understood it clearly..now trying to make an AVL tree for more number of Nodes :)
Yes, you can, and my next topic will be making AVL tree from more no of nodes in BST!
bro plss also make videos on heaps, m way trees , b trees , red black trees , graphs ...plss bro ....love your videos
Will cover them soon!
When this course will be completed?
Will take lot of time :-)
Bro plz upload the tries data structure video also
bro if you don't mind ......would you please post as a reply what all the topics that you are going to cover from now.
In this playlist, the first video has the list of probable topics. But I think its going to be much more than that. DSA is a very huge subject so there is no end limit as of now.
Trees, Graphs, Hashing some traversal algos are left but this is already a lot.
You have a big mistake. you forgot to put the negative sign for the numbers. In 1 it's -30, in 2 it's -10, in 3 it's -30, in 4 it's -10
i think the - in front of the numbers, is just to differentiate between text and numbers, like "insertion - 10, 20, 30", and the number you need to insert is 10, 20, and 30. you can skip the -.
Time waste
