@TheAntloo, how many times have you used an AVL Tree in your job of two years? 🙂

This kid's older brother is one of my little homies from college. Now i'm reviewing algorithms and the little little homie is teaching me. Both impressive young men who are making their families proud.

Looks like this homie stopped the videos because there is no money in teaching for free. That means he gained wisdom and is using his knowledge to make a profit instead... Homie is getting wise.

If there are any mistakes let me know and I'll update the "Errors" section.

This is the clearest explanation I have seen on Balanced Trees so far. I was trying to learn this topic back in march and I could not find a good resource to understand and I dropped this topic. Now today I picked it back up and I found your video. Thank you so much !! ---> Subscribed

Before i watch the video again gotta let you know, this was hands down the best illustration ideo for AVL trees. The illustrations are easy to follow. Cheers.

OMG the way you explained it around 12:30 makes so much sense. I don't need to memorize anything, I just need to think through whether each triangle is less than or greater than x, and the same thing for y, and then it's so easy to perform the rotation. Thank you!
