I tried solving problems from Kattis Online Judge and Online Judge (UVa) but I'm barely able to solve problem A and B in codeforces Div 2 round. I had high hopes that I would be able to get good this year but it is not working out. I've been doing CP for around 10 months. I'm not able to approach C and D problems at all. They use some crazy dp bitmasking logic which goes over my head. Rant over
