Hi, I am currently doing CP from 4-5 months, now in contest on HackerRank and HackerEarth. I am able to solve 3 question out of 7-8. So basically I am stuck on medium questions, sometimes medium difficulty questions can be solved but mostly not.

So can you please tell me approach to improve, and also I am very week in topics like greedy and DP. So what should I do improve?

Thanks for conducting session.
