I started CP and DSA last year around December 6th or so. From then I have mastered cpp stl and can code most of the probs after hearing the logic. I have done a lot of probs on recursion,dp, and binary search on answers. Currently, my standing is I can solve 2 probs in Div 2(mostly). Can anyone suggest new topics or patterns so that I can attempt most of the 3rd question in cf div2?
