For those who solved Q3 today, how do y'all manage to become proficient at greedy like the one today at biweekly Q3?
Every time I stumble on a greedy observation question variant, it's just novel with a different observational pattern shape as if each greedy problem got its own pattern. Of course I learn, and I keep in mind of those shapes, observations to look for and patterns appearing for every next greedy I encountered. Aside from doing more, do you like drill your thinking process, or drill something else?
