VMSS Pre-Pre-Windsor Competition

To start off the year, VMSS will be hosting their first contest, the Pre-Pre-Windsor! Anyone, even if you're just starting off with computer science, is welcome to join.

The problemsetters are Medi and HDCat.

This contest will not be rated.

Before the contest date, you may wish to check out the tips and help pages.

This contest will consist of 7 main problems, each problem around the difficulty of CCC Junior.

You will have 90 minutes to complete the contest. After the contest window begins, you may begin at any time. Once you enter the contest, your personal timer will start counting down and you will be able to submit until 90 minutes from when you started, or until the hard deadline (12:00 AM EST of Oct. 18th), whichever comes first.

After joining the contest, you proceed to the Problems tab to begin. You can also go to Users if you wish to see the rankings.

We have listed below some advice as well as contest strategies:

  • Start from the beginning. Ties will be broken by the sum of times used to solve the problems starting from the beginning of the contest. The last submission time of your highest score will be used.
  • It is not guaranteed that the problems will be in order of increasing difficulty. Reading all of the statements is recommended.
  • Remove all extra debugging code and/or input prompts from your code before submitting. The judge is very strict — most of the time, it requires your output to match exactly.
  • Do not pause program execution at the end. The judging process is automated. You should use stdin / stdout to perform input / output, respectively.
  • It is guaranteed that all the problems will be solvable with C++, Java, and Python.

At the end of the contest, you may comment below to appeal a judging verdict. In the case of appeals, the decision(s) of DMOJ staff is final.

      I think this is because to prevent people from hardcoding it.

        You can have batches to prevent hardcoding, or you can hide the output.
