Any user can request the creation of a Contest.

The user who solves the most problems of a contest will be the first. In the case of a tie between multiple users on the number of problems solved, the user with the lowest total accumulated time will be the first. Accumulated time is the sum of time in minutes since the beginning of the competition until first accepted answer for each problem, adding 20 minutes (configurable) to each wrong submission sent previously the accepted answer, if exists.

For example, if a team submit:

• a correct solution for problem C (minute 41)
• wrong solution (WA) for problem A (minute 50)
• wrong solution (WA) for problem A (minute 53)
• a correct solution for problem A (minute 55)

The sum of time to this team will be 41 + 55 + 2 penalties (40 minutes) because problem A was accepted just on the third tentative. Total: 136 minutes. If another team solve the same two problems with an accumulated time equal to 135 minutes, this team will be in front of your team.
