I am a professor in CSE deptt. But, I learnt almost every lecture of Data structure from your channel and then get a confidence to teach my students. Keep it up. God Bless you. Certainly, u shall reach the height.

Point to remember: If rotation is LL or RR, then GP and P node will be recolored, if rotation is RL or LR then GP and Child node is recolored. GP means grand Parent, P means Parent.

Oh my gosh this explanation has made it so clear !!! I was struggling badly. Thank you x

[@sohamshinde1258]

Ma'am you taught it very nicely. Also your algorithm is very helpful, but I would like to have some edits as follows : 1) If tree is empty, create newnode as root node with colour Black. 2) If tree is not empty, create newnode as leaf node with colour Red. 3) If parent of newnode is Black then exit. 4) If parent of newnode is Red, then check the colour of parent’s sibling of newnode: a) If colour is Black or NULL then do suitable rotation among node, parent and grandparent and then recolour the parent and grandparent. b) If colour is Red then recolour the parent and parent’s sibling and also check if grandparent of newnode is not root node then recolour if and recheck from the grandparent.

[@dineshumar1439]

Just wow!! Very well explained. Everytime when i have to study any topic i just simply write topic name and then by Jenny. You are my first priority.

[@reshmareshu1194]

Yes mam! If every node has black it can be red black tree And also check the number of black nodes when traverse in every path!! Thank you so much for the clear-cut explanation 😊❤

[@HornOKPlease]

You're so good at Data Structures, you can pass any interview - wow

[@hassanelnaggar3647]

Here are the algorithm notes written on the board: 1. If tree is empty, create newnode as rootnode with color Black 2. If tree is not empty, create newnode as leaf node with color Red 3. If parent of newnode is Black then exit 4. If parent of newnode is Red, then check the color of parent’s sibling of newnode: (a) If color is Black or null then do suitable rotation and recolor (such that the root of the subtree is Black and children are Red) (b) If color is Red then recolor (parent and parent’s sibling) and also check if parent’s parent of newnode is not rootnode then recolor and recheck rules: -> root color = Black -> no two adjacent Red nodes -> count of Black nodes in each path is equal

Yes, Every node in Red Black tree can be black, but i guess the tree must be perfectly balanced so that there will be same number of black nodes in each path.

Yes! If every node in a tree is black can be known as a red black tree; But that tree should contain the same number of black nodes when we traverse across every path of the tree.

Never forget that the 'Rechecking step' is only required for the case of 'Uncle is Red & Parent is Red'. It's because only this case is the situation where the internal Black node becomes Red. The other case, where the uncle is black, this 'Rechecking step' is not needed. It is important to know this when the actual implementation should be done.
