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.

it is one of the toughest section in the DS. .. you worked extremely hard for this....quite evident from the video...🙏🙏🙏

[@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]

Wahh

[@dineshumar1439]

In 4(b).......then recolour it and recheck...

[@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

Ur videos are clearly understandable thank you, Mam I have a doubt the red black tree has a property(i.e longest path from the root is no more than twice the shortest path),in the above example shown by you after inserting node 30 the red black tree u get violates the above property then how could it be proceeded to insert 25

Thank you so much mam for uploading this red -blcak tree video . You are the best

[@satyajitdeb5661]

Sorry for being here late. So in your question you mentioned that the tree is already a Red Black Tree, therefore it is already adhering to the properties of RB Tree i,.e Root is Black, No. of Black Nodes in each path is equal. Therefore, yes all nodes in an RB Tree can be black. I hope I am correct

[@bothsapriyanka3540]

Tq for this video mam... Answer for your question is YES in red black trees we have all nodes in black...

[@mallikblue]

Mam after inserting 16 there is LR rotation rt. After doing rotations recoloring na. At that time recoloring of new node should do or not. I got a doubt

[@sujitsahoo3081]

yes.there is recoloring. Ideally while rotation the super parent of all the 3 nodes will be black. So while rotating to the place of super child will become black. and other two will be red. So here recoloring done.

[@vasusuryavamsham4882]

New node should not be recoloured in any situation,it should always in red colour
