Hi Codeforces!

From Saturday, July 31 00:00 EDT to Wednesday, August 4 00:00 EDT, we will be hosting An Animal Contest 3 on DMOJ. Participants will be given a 3-hour window to complete 8 problems themed around monkeys. The problems are in roughly ascending order of difficulty ranging from Div. 2 to Div. 1.

To participate, you must register an account on DMOJ.

Some additional information about the contest:

  • The contest is full feedback and there will be no pretests or systests — you will be judged on all test cases. Moreover, there is no hacking.
  • The contest scoreboard will be hidden until your window is over.
  • All problems are guaranteed to be solvable in C++ and Java.
  • The exact start time of the contest in your timezone can be found here.
  • This contest is rated for all participants that enter the contest, regardless of whether or not they have submitted.
  • Checkers: unless otherwise specified, identical. The contest will follow the standard convention of having all lines terminate in a \n character, with no trailing whitespace.

More information can be found here. We hope you enjoy the problems and have fun!

UPDATE: Contest end time has been extended by a day!

UPDATE 2: Contest window is live!

UPDATE 3: The contest window has recently ended. We thank everyone for participating!

    The contest is windowed meaning in the time frame from July 31 00:00 EDT to Monday, August 3 00:00 EDT, you will be able to select a 3 hour window to do the contest. Once your time ends you can no longer earn points for the problems.

    Please forward all your clarification requests through the ticket system in DMOJ as it says on the contest page:

    Clarification requests for the contest must be routed through the clarification system provided on DMOJ, and not through other channels including but not limited to Discord and Slack. Furthermore, all clarification requests will be handled the way they normally are in IOI. Note that, in particular, clarification requests must come in the form of yes/no questions.

    It means you've had some problem with formatting your output.

    Check to see that you end each line with a newline character (i'm pretty sure this applies to even your last line), and that you don't have any unnecessary spaces.

    For example, during the contest, I had an unnecessary space after the first line of my output for the third problem, which gave me presentation error.

    Good luck!
