i've practiced a lot of problems about greedy/constructive/implement/math,but still feel tough when facing a new problem with these tags.
i find practicing these tags makes me frastrated because i cant get feedback,like"i ve practice this tag a lot,so i can solve them easily".i can get such feedback in other tags like some specific algorithms or data structures,but cant find it in greedy/constructive/math
should i skip these tags and try other tags instead? or keep on them until conquer it?
If that's your weakness then grind on that part. Like imagine during the time when you were a kid and unable to walk, your parents forced you to do FFT. You are not supposed to skip stuff.
Ayo don't disrespect Stephen Hawking
You should not skip any particular problem tag at all(Specially if it is greedy/constructive/math/implementation because they appear a lot in the contests of codeforces). You should not stick with a single tag for very long either. You are not supposed to conquer those tags any time now , it requires a way lot of practice. It's a good sign that you're comfortable with algorithms and data structures. But as a beginner it's more efficient if you focus on greedy/constructive/math/implementation. If you fell frustrated you can try different tags for a while and try those tags latter.
