The first thing that we want to bring to your attention is about how to register for the contest. At first, you need to create an account for your team on our subdomain in the upper right corner. Please, share this account with your teammate. Note that this it not an account for codeforces.com. Then, you can go by contests link and register for the contest as individual. After that you can participate without any issues.
Please, get familiar with the system and try to solve the test contest.
P.S.: if both teammates have codeforces accounts (on the main website) you can create a team with them and participate as a team.
Now, we share with you some tips that should be important during the contest.
If you choose to write solutions in Python
At first, we suggest you to submit your solutions using not "Python 3" language but "PyPy 3". It is much faster and can make a large difference. Almost all our problems can be solved in Python, but with PyPy compiler.
Secondly, there can be issues with the slow input. (Hope it will not be the case.) So, we would suggest to use sys.stdin.readlines() to read the whole input as lines.
import sys
...
lines = sys.stdin.readlines()
...
If you choose to write the solutions in C++
C++ also has some issues with the slow input. To solve it we refer to this link.
If you choose to write the solutions in Java
Java also has the same issues. To solve it we refer to the third option by this link.
