Welcome to the second Generic Computer Contest!

The problem writers of this contest are Kirito and r3mark.

The GCC will be a 3-hour virtual contest, which will allow contestants to participate in any 3-hour window between Apr 1, 12AM EDT and Apr 3, 12AM EDT. It is forbidden to use two accounts to participate, and it is also forbidden to discuss the problems and/or solutions with other people during the entire contest period.

The contest format will use the AtCoder contest format.

This contest will not be rated.

Before the contest date, you may wish to check out the tips and help pages. The contest consists of 3 questions with 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 the problems may range 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 (Apr 3, 12AM 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:

• 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.
