Well straight to the point. I can't afford online programs on DSA (expensive for me). I generally Google all my doubts, but sometimes I don't get my doubts clarified. Although whenever I have posted something on codeforces, most of the time my doubts are cleared.

I feel it would have been much better if I can contact some specialist, expert aur candidate master (preferably on Messenger)with whom I could have shared my ideas on problems.

Currently my rating is 1276. (Had to mention this because I have not mentioned pupil above).

I would be thankful if someone is willing to help me . Thanks in advance :).
