TLE '16 December Contest

Welcome to the fourth Trudeau Logic Evaluation of the 2016-17 school year!

The problem writers/testers of this round are ZQFMGB12, d, and nathanl3.

The TLE will be a 3-hour virtual contest, which will allow contestants to participate in any 3-hour window between 12:00 PM EST, December 23, 2016 and 11:00 PM EST, December 24, 2016 Of course, it is forbidden to use two accounts to participate, and it is also forbidden to discuss the problems and/or their solutions with other people during the entire contest period.

The contest will use a pretest/systest format for problems 4-6. When you submit to these problems, you will only be judged on some of the test data, called pretests. After the contest, all submissions will be rejudged on the full test data. Pretests typically contain weak test data and do not include maximum or corner cases. Unlike other pretested contests on the DMOJ, problems 4-6 will have a pretest score out of 100 instead of 10.

This contest will be rated for all participants who submit at least once.

EDIT

The top 5 participants and the top 2 Trudeau participants will receive a free Trudeau Computer Science t-shirt as a prize! If a Trudeau student is in the top 5, that student is counted in the top 5 winners but not the top 2 Trudeau winners.

Top 5 winners will be e-mailed shortly after the contest for additional details via the e-mail the account is associated with.

If you are a top 2 winner from Trudeau, please send an email to petcompsci1@gmail.com using the email account associated with your DMOJ account. Attach your DMOJ username and a photo of your entire 2016-17 PETHS student ID card.

Winners must respond by Thursday, January 5, 2017 11:59PM EST in order to claim the prize.

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

The contest consists of 6 questions with a wide range of difficulties, and you can get partial marks for partial solutions in the form of subtasks. If you cannot solve a problem fully, we encourage you to go for these partial marks. The difficulty of a problem may be anywhere from CCC Junior to CCO level. You will have 3 hours to complete the contest. After the contest window begins, you may begin at any time. Your personal timer will start counting down, and you will be able to submit until 3 hours from when you started, or until the hard deadline (December 24, 23PM EST), 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.
  • 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++.

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