Wesley's Anger Contest Rejects

It is well known that wleung_bvg is always angry. To vent out his anger, he decided to create yet another contest out of problems rejected from previous WACs!

Here are the parameters of the contest:

Contest duration: 3 hours.
Number of problems: 6, full feedback. Each problem will be worth 100 points, with some problems offering partial marks in the form of subtasks.
Rated for opening the contest. Unlike with other contests which require making a submission for the contest to be rated, opening the contest and being able to read the problems will cause the contest to be rated.
Scoreboard will be hidden, until your window is over. Divulging the contents of the scoreboard to participants who have not finished their window is an offense, the punishments of which are listed below.
No submission penalty.
No submission limit.
Ties will be broken by the last submission time that increased your overall score.
Checkers for problems: Unless otherwise specified, identical. The contest will follow the standard convention of having all lines terminate in a \n character, with no trailing whitespace.

Due to rampant issues with cheating on contests that has happened recently, any suspicious behavior during the contest window may result in your rating being impacted negatively. Such behavior includes, but is not limited to:

Divulging the contents of the scoreboard to participants who have not finished their window.
Registering for the contest with at least two accounts.
Participating in the contest with an account that is not your primary account.
During the contest window, talking about the contest in more detail than answering a yes/no question about whether one participated in the contest. This includes, but is not limited to, posting spoilers about the contest and public speculation of the contest.
Attempting to exploit bugs in the platform to subvert the constraints of the contest.
Attacking the judge infrastructure, other contestants, or contest personnel within or after your window.

Punishments may include performance being unrated or, for more serious infractions, being forcibly ranked at the bottom of the scoreboard.

The problem setters for this contest are wleung_bvg and Pookmeister.

Special thanks to Dormi, crackersamdjam, Plasmatic, Zeyu, aeternalis1, Riolku, piddddgy, JoshuaL and MstrPikachu for providing feedback and testing the problems.

A special thank you to maxcruickshanks and Ninjaclasher for their administrative assistance and feedback with the contest.

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

This contest will consist of 6 problems, the difficulty of which is similar to a typical Wesley's Anger Contest. The problem order has been randomized.

You will have 3 hours to complete the contest. After the contest window begins (April 1st, 09:00 EDT), 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 3 hours from when you started, or until the hard deadline (April 1st, 23:59 EDT), whichever comes first.

After joining the contest, you can 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:

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++. All problems have a time limit of at least 2x the reference solution, which is written in C++ and uses this template for I/O. If you're unable to see the template, you must solve this problem. Problems that have been tested in multiple languages may have language specific time limits.

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.

This contest cannot be rated as it is not at the same level of quality as other rated contests. As you may have noticed, this contest was created out of rejected problems from previous WACs (some were around since WAC1!).

We still plan to have one final contest (the real WAC7) soon $^{TM}$ ~^{TM}~.

This comment is hidden due to too much negative feedback. Show it anyway.

Yikes, that does not seem to be a popular decision :P You really should not run half-serious contests on April 1st. Would recommend making it clear whether it's a joke contest or not at the latest by when a contestant opens the problems.

The contest format has changed. There will only be $6$ ~6~ problems and the window is now $3$ ~3~ hours long. The scoreboard is also hidden for the duration of your participation. We would also like to remind contestants that the problem order is randomized. Good luck!
