Hi admin, look at these solutions.
These solutions were submitted by a single user in span of just 1 min. How it is possible for an user to submit entirely different solutions in a short time. Clearly this is case of cheating and the user name itself tells a different story. These cheap people are ruining the spirit of contest. I request admin to delete those fake account and validate IP address of the fake user and delete those accounts as well who are using codechef with that same IP.
