I've started a YouTube channel called "Algorithms Conquered". I uploaded a video on segment trees to see how it goes. I am thinking of uploading videos on problems on segment trees and different ways in which we can use segment trees and well as educational dynamic programming problems (not classic problems but problems which will improve your understanding of dp in general).
I'd appreciate if you can check it out :)
Also, if you have any video ideas or want to learn something do let me know in the comments!
