No teacher taught Red black tree by actually using Red and black markers which made it difficult to understand. You did it neatly and your explanation adds clarity. Thank you for this video ma'am 😊😊😊

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.

[@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

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.

In LL or RR case,the parent and grand parent must be recolored. In LR and RL case do L and R rotation and follow the same as LL and RR case

[@dominicjung4950]

Great lecture ma'am. I really appreciate it again 😊 btw I had one question that's a bit theoretical. In AVL tree if you insert ordered (2**n - 1) items to the tree, it automatically balances itself to be a "perfect tree". That is if you insert 15 items your tree will be 4 level-high exactly (1+ 2 + 4 + 8 = 15). The tree will be skewed at first because you insert ordered items which are added only on one side of the tree but due to AVL's balance factor they will be balanced to a perfect tree at the end. And from here if you delete items very carefully so that no rebalancing function is invoked at deletion, you can theoretically create all possible AVL tree configurations. Now my question is: is this also possible in RB tree? I mean: is every valid RB-tree creatable using only RB-tree insertion and deletion algorithms in these 2 videos? Because if there are cases of RB-trees which are not possible to create using these insertion or deletion algorithms I think the whole idea behind RB-tree is somewhat pointless. Because it's like saying it is a valid RB-tree, but mathematically proven there is no way to create that tree using RB algorithms. This question is purely from my curiosity while delving deep into studying this. Anyone's answer would be welcome! 😊 Thanks a lot.

[@dominicjung4950]

Btw I couldn't find the proof about this yet, but did find the link of someone who asked the same question on Stack Overflow. stackoverflow.com/questions/11647042/can-every-valid-red-black-tree-exist In case anyone is interested.
