Don't you think convex hull optimization is a bit too early to learn at your current rating?

      Actually, he has a point. There are other "simpler" stuff that you should learn if don't know them already. You should also practice those simpler concepts before you move on. I was already purple when I learned convex hull, and honestly, it is used much less than things like segment trees, sqrt decomposition, and dp.
