bruh, we need to get better at solving problems, here are some tips to help: when u open a problem, u need to not be lazy if its too hard for u; better just solve it. also u should train ur weaknesses, for example mines is math, so i need to filter problems on math. Remember, in coding u shall not have a weak side. and also dont ONLY do div 3, 4. do div 2 too, because if u solved a few problems u might have seen that some 800-1000 ratings problems are from div 2! also most ABC problems in div 2 are math so u should strenthen it, and not make it weaker like me (;

If u agree please like cause ive got -47 there!
