It is very sad that you stopped making those amazing videos...

DVZM.

You didn't get enough credit for these, they are appreciated it.

I love the conciseness of these videos, Michael! Keep up the great work! One recommendation I have is to make the pseudocode you provide more approachable by re-labeling the variables to match your diagrams.

Please post the video of Red-Black Tree Deletion as well

I've read elsewhere that the maximum height of a red-black tree is 2 * log(n + 1). This is not to say that this isn't a fantastic series of videos, because it is and they've helped me substantially! Thank you for that!

You make great videos about algorithms. Please keep it up and produce more videos like that! Short, easy and very helpful.

Your videos are awesome! Straight to the point and short compared to the others on youtube.

Dear Michael, Thank you very much for this video. You are my saviour :)

The other important fixup for Red-black trees is recolouring.
A combination of recolouring and rotation is done on inserts & deletes to fixup red-black tree violations.
Fixups go in the direction of the root node.
For Insert, a maximum of 2 rotations are required.
For Delete, a maximum of 3 rotations are required.

Bro thank you the explanation was so good you saved me👍👍

in few years if you will hold this level of video's you;ll be number one youtuber of informatics xD

Useful, thanks so much, I was confused on rotating but it's actually simple

DavidEspinosa

ok, i can understand why you rotated the 10, 5, 2 and the 12 since they're all connected. But why did you flip 8 to the other side of the tree?? No explanation. Just confused. Even if you keep the 8 on the same side in either rotation instead of changing it to the other side, it would still be balanced.

your videos are very helpful, keep up the good work!!

I wish it was explained like that in data structure lectures. :D

By doing a rotation we are simulating the right order of inserting node

_mrix_

so if I understand and did it correctly, is the solution to the the tree shown at 0:22 this?
