do a lot of C problems

My personal advice (but maybe you'll find better strategy): read editorial after 10-15 minutes of not having new ideas (not after e.g. 15 minut spent on task). Then code it.

    But do i need to learn some advance algorithm like suffix tree or kmp?Or shall i just focus on solving some hard problems from those topics i have already covered? One more thing,i already tried to solve some C problems from previous rounds,sometimes it seems too hard for me to understand the tutorials.Then if i see the solutions of others and try to learn how they solve it is it a good idea to develop my skill?

      Div2-C tutorials are often bad written because they are div1-A and they're easy for author. Or maybe you don't have enough programming/math background? Articles about algorithms and books will be helpful then. And read this

        Yes my math & programming background is not that much good.I just started programming two years ago,and started participating in contest 6-7 months ago.But i'm trying to work hard and ready to give everything i can now to fill the gaps.Thank you so much for your help :)
