I can solve some pretty tough problems involving DP, graphs, and data structures. Sometimes I can handle problems that feel much more “advanced” technically.
But strangely, when I face some Div.2 A/B/C problems, especially greedy, constructive, or adhoc, I often get completely stuck . This kind of observation feels very different from DP or graph problems. In DP, I usually ask: What is the state? What is the transition? How do I optimize it?
But in these small constructive/greedy problems, I dont know what to do or coul not think of any solutions that i have approached before . How can i fix this bugs ?
