This is a convex hull trick problem. I am building my convex hull from leaf to higher nodes. Every time I am going through all my child nodes, I am merging them together. In this solution, I am not applying light to heavy technique. Because of the increasing CHT size, I would expect my solution to get TLE on the given constraints. But for some reason, it's not getting TLE. Anyone got any proper explanation?
