i just love the way RB tree is taught.I m a student of computer science engg. and i would love to attend such lectures live.
this is the way learning can be made so easy and simple.
and i would love to be in contact for further problems and topics

Hello everyone,

very, very interesting lecture. But above all, it is given in a such an understandable way that I just could not resist to say "Thank you, MIT!" :)

I wish our lecturers were teaching like this as well... We have some (like, two - three of them) who are capable of such a teaching, but the others seem to just "do the dirty job". They do not try at all to make it interesting, easy to understand... They completely disregard how intelligible it is to their audience.

This is very very effective way to learn data structures.I love the way it is taught.I wish even indian universities should adopt this.

I think the guy made a mistake while describing the general algorithm for RB-INSERT. For CASE 1, he does not consider the color of the parent of x (the node to be inserted); and blindly recolors x's uncle/aunt if it is RED. This should have been done only if x' parent was RED as well. And the Trick here is, if X' parent ain't RED, we don't need to do anything to maintain the RED-BLACK property.
The CLRS book gives the correct algorithm, where the while loop runs over the color (RED) of the parent of X, rather than on X itself.

he seems to be a great teacher..totally cleared my head..but i waslooking for deletion in RBtress..anyone has an idea where i'll get an equally good video to understand how deletion works?!!

i got this lectures very useful !! got wat exactly a RBT is , thanks to MIT

@10:30 - he draws node X which descends in 4 paths to bottom but a node points to only two sub-nodes (left, right). That can't be right. It should look like a tree imho:
x
/ \
y z
/ \ / \
a o e u
^ ^ ^ ^

AS I understand, RB tree is balanced. When I say, I understand it to be height balanced. The tree example that is being worked out is not balanced.

18 Pardeep, January 16, 2015 at 10:24 p.m.:

just Awesome! Today I understand the RB trees
