First i have an issue and i really need your help. issue is i recently joined competitive programing and i tried to join many Codeforces rounds but every time i lose rate and i searched for the main reason why i lose rate .
It's because every round i start with A and when i try to think for solution my brain gives me a hard one even for simple problem so i lose time and cant get a solution.
So. Can you guys tell me some tips to think about solution for Div2 A,B,C Ex. as i saw most of C problems need data structure most of A problems focus on Implementation
E.x sometime i can think for graph solution when the problem need a simple brute force
