All the codechef problems that I have solved till now. Copyright© 2016 by Harshit Budhraja.
Please feel free to fork and go through these solutions and correct the wrong ones and do open a pull request so that I get the correct solution too. P.S. A humble appeal, please do not submit these on codechef in your name, as it won't benefit either you or me. It would just take away your self-dependency and hide your capabilities from your own self.
