There are 11 problems worth a total of 179 points. Each problem will require either submission of your solution source code to Codeforces, or submission of the files comprising your solution to Dropbox.

Follow these instructions for submission to Codeforces:

• Create a Codeforces account if you don't have one already. Use only one account per team.
• Submit this form with your Codeforces handle.
• Go to the COSCON Codeforces group page and click "Join". Then click "Register" next to the contest named "Princeton COSCON 2023", and then click on the contest to see the problems. See below for the problem statements; you won't be able to see them on Codeforces.
• To submit a solution, go to the "Submit Code" tab, pick the problem, the submission file, and the programming language, and then submit. Judging will take a few seconds (refresh to see the result). You can submit as many times as you wish. You can use C++, Python, Java and many other languages to write your solutions.

Follow these instructions for submission to Dropbox:

• Go to the Dropbox File Request link for the problem by clicking on the appropriate button below. Click "Add files" and select your solution file(s).
• Your solution files must use the name format: [Team ID]_p[Problem number].[Extension]. [Team ID] should be replaced with your provided team identifier, [Problem number] should be replaced with the problem number for which you are submitting a solution, and [Extension] should be the usual file extension based on the file type. For example, a3f8_p10.txt.
• If required, enter the name and Princeton email address for any of your team members under "Your name" and "Your email address", and then upload.
