Hello Codeforces!

On 12.12.2020 22:00 (Московское время), the CodeRams Algorithm Contest #1 will occur. This is the first algorithm contest of the year for the CodeRams, my school coding club. We've held many contests over the past several months, but since this one is more like a Codeforces round, we've decided to open an online mirror of the contest on the Codeforces Gym.

The contest will contain 9 problems, and you'll have 3 hours to solve them. The first few problems are fairly easy, designed to be solvable by anyone, while the last few are more difficult. The contest will likely be more interesting for users with a rating of under 2100, but anyone is welcome to participate.

Each problem in the contest has a point value, with harder problems being worth more points. Contestants will be sorted first by their total number of points, and then by their solve times, if there is a tie. Some of the problems will also have subtasks and partial scores.

All of the problems for the contest were created and prepared by me (plourde27).

Thanks to Alx, eggag32, and galen_colin for testing the contest. Special thanks to galen_colin for helping me fix an issue in one of the problems.

Finally, thanks to MikeMirzayanov for the great Codeforces and Polygon platforms. Being able to hold mashup contests on the Codeforces Gym has been really useful for our club, especially since the start of the COVID-19 quarantine.

The score distribution will be announced later.

UPD: Note that the problems from this contest will be different from our past problems in the Codeforces Gym archive, since those were made for novice-level contests last year and are mainly implementation based.
