So I have a YT channel and I did a coding challenge(like coding train) to visualize the building process of a segment tree in 15 mins. I also explained briefly what segment trees are (In case you don't know what it does).
I figured it can be relevant/helpful to people here as Segment trees are mostly used in CP.
So if you'd like to see for yourself, link: https://youtu.be/nM16pnE1ayQ
