Since, the contest was of Division 4, problems were a lot easier as compared to other contests. So, solutions of simple problems are pretty straight forward. Unfortunately one of my submitted code significantly matched with another person (ashutosh_1718) and thus Codeforces skipped my contest. Neither I used any online public compiler nor I know this person. It was really a devastating moment for me when I saw the notification sent by system to me because in this contest I was able to solve 6 problems out of 8 for the first time.
