I have a Facebook page where I try to post my approach to the problems I solve in any contests. I created this page for two reasons, First, to revise any new things I may have learnt during the contest and second, to help any new users/medium users to learn new things. I try to answer to as many doubts as possible. If you think, the page would help you feel free to like and follow the page. “https://www.facebook.com/algo0111/posts/200339503784614”.
