Welcome to this year's Richmond Green Programming Contest! You've probably been studying really hard for the upcoming CCC, so why not try your skill at a contest?

Users will be given a 3-hour window between 12:00 PM EST on February 17, 2017 to 11:59 PM EST on February 19, 2017 to allow as many users as possible to participate. There will be five problems of approximately increasing difficulty, varying from CCC Junior to CCC Senior, and full test data is used, meaning no pretests/systests. Due to the large time window and easier difficulty of the problems, this contest will be unrated.

You can think of this contest as a cool-down to DMOPC February or as a warm-up to Trudeau's Mock CCC. Problems will be approximately the difficulty of the GFSSOC '17 Senior contest.

The problem writers are chenj, Dankat, and NeatMuffin. All problems are guaranteed to be solvable in C++.

Tips for this contest

• Write this contest as if you were actually writing the CCC; this will allow you to mentally prepare yourself
• Read all of the problems carefully. Some may not be as hard as they seem, and misreading can waste a lot of time
• Attempt all of the problems. Harder problems are broken down into subtasks to allow you to get partial points

You will have 3 hours 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 3 hours from when you started, or until the hard deadline (11:59 PM of February 17), whichever comes first.

After joining the contest, you proceed to the Problems tab to begin. You can also go to Users to see how quickly other users completed the problems and how you compare to them.
