identical
. The contest will follow the standard convention of having all lines terminate in a\n

Clarification requests for the contest must be routed through the clarification system provided on DMOJ and not through other channels, including but not limited to Slack or Discord.
Before the contest date, you may wish to check out the tips and help pages.
The contest consists of 5 questions with a range of difficulty from JOI 2005 Final Round Problem 1 to JOI 2005 Final Round Problem 5. It is highly recommended to read all of the problems. 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, 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:
- Start from the beginning.
- Remove all extra debugging code and/or input prompts from your code before submitting. The judge is strict — your output must match the judge output 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++.

Comments
Problem 1 you need to put an endl at the end of output for some reason
Why does my code not work for P3? https://dmoj.ca/src/6912922 Edit: Never mind, I found the problem
Is P4 NP Hard?
This comment is hidden due to too much negative feedback. Show it anyway.
It's because its answer is wrong on all the test cases. Hope this helps.
First time, I saw a list of problems and opened the first problem. When backed to contest page, the problem list disappeared. NVM - Press Problems on the main menu
