Hello guys, I am currently a newbie on Codeforces. I wanna give NOI next year and will start preparing from February 2026. I wanna know how to get good most efficiently, like I know just solve problems, but still, how to? Do I sort the problem set by difficulty, then if I see a new algorithm, how much do I learn about it, like the very advanced stuff about it, or just the basics and also what would be a good estimate of questions to practice daily? Any strategy or guidance would be greatly appreciated Thanks
