I am studying IT in Australia currently. This is the first video I found on Red-Black trees where I actually understood the topic because you start from the basics and give lots of examples. Thanks and gratitude from Australia! Also, the last question tree is not Red-Black because the left NIL child of 15-node creates a black path that is of different length. Very good question, makes a person think deeply. Keep up the great work!
This is only true for people that already know exactly what to study to learn what they want to learn. Otherwise I can't see how someone who has no prior knowledge would even know to search for this video or have any appreciation for it. I suppose someone could read an introductory textbook but most people don't do that.
Seriously.....you are too good at teaching....I rarely appreciate people....but u deserve not only appreciation but also a heart❤️❤️... Thankyou so much ma'am for your precious teaching...🙏🙏
Awesome lesson, as answer to your question @ 32:43, it's not following 4th property as there is a left NIL node of 15 having only 1 Black node from root to NIL leaf node, all others have 2!
If you're following the DSA textbook by Goodrich, Goldwasser, and Tamassia, the violated property is also called the depth property ('ALL nodes with zero or one children have the same black depth whereby a black node counts as it's own ancestor') which is violated by node with key 15.

Thank you very much mam, i was waiting for this lecture especially from u n finally it's here. And getting to ur question, this not a RB tree, bcoz it's violating the last condition i.e. the no. of black trees are not same.
Insertion in AVL tree takes a maximum of 2 rotations. Deletion can many rotations. Hence, Red Black trees are used if insertion & deletion operations are very frequent
Thanks a lot Ma'am. You are amazing 🤩🤩🤩 Just Because of you I understood Data Structure last year .... And now finally I found your videos about DAA... 😁😁
I was unable to explain this topic in Geeks for Geeks interview, although I am good at competitive programming. But you explanation is quite good. I knew the concept already but now I can explain it to anyone. Thanks a lot ! (I wish you were my teacher, so pretty) .
The node with value 15 has no left child and total number of black nodes to the path 15 -> NIL is 0 while to the path 15 -> 25 -> 20 -> NIL is 1 and such further paths . So , not a red black tree.
I feel like an expert in red-black trees now haha, and I’ve never read anything for more than 2 mins about it. So, the last example is not a red-black tree, because in the right side you have a path to a nil with only one black node, and the others have 2 black nodes. Still a little bit confused on usages, although the properties of self balancing are pretty cool, I guess that’s what the red or black abstraction is for. Thank you! Keep up the good work!
20:53: Jenny introduces a 12 node to black path count is 2. But without introducing a node, make 15 black, 20 red. It becomes a red-black tree and all paths have a black path count of 2.
Hi All my life I feared datasturcture until I came across your channel. Thank you so much. About the question definitely its not a red black tree because, the no of black nodes from the root to leaf nodes is not constant. From left if I consider nil then the no of black nodes are 3, but the right sub tree it's 2 (If a black node is consider after 15 (Red).Did I get it right? 👍 from Bangalore
The last tree is not Red Black because the path from root node 10 to node 15 (which has left node null) contains only one Black node whereas every other path has two black. Correct....?
@@guruprasad280 In right Subtree, Check for Node 15 having Nil on left. Hence there will be only one Black to that Nil path. But other paths have 2 Black nodes. So It will not be Red Black Tree

India needs these kind of people for educating other's for free of cost
Really Great Lecture.. Not found this much information any where,, Many thanks from Germany
32:45 It os *NOT* Red-Black tree. Because it is voilation property of every path has same Black Nodes. (At node 15 path is having only 1 Red Tree).
Shortcut:
If a red node exists it shouldn't have a single child
It should always have 0 children or 2 children

Iam not understand English properly but your speaking iam easily understood you have awesome English skills mam ❤️
Mam love you .. excellent teaching
Hi Mam, @22:52 this is actually a BST. It didn't violate BST condition, instead it violated the condition "root node can't be red"
Take your notes at 32:48 (rules for Red-Black trees)
The last tree is not Red Black because the path from root node 10 to node 15 (which has left node null) contains only one Black node whereas every other path has two black.
Correct....?
