Hi Codeforces Community!
I and Sweet are excited to invite you to our contest, [contest:527272], which will start in [contest_time:527272]. Please note about the unusual time for our contest!.
Note that our contest is unofficial, so it's unrated. Furthermore, because all of us won't be able to do the contest in Codeforces gym, we made our own contest in Codeforces Mashup. Here is the link of our contest: Link
You will have 2 hours to solve 6 — 7 problems in the contest. The contest will be held in ICPC format, with penalty of 10 minute for incorrect submision. The range of difficulties of the problems are from ~1000 to ~2000, based on some tester feedback.
We guarantee that all of our problem will be unique and interesting. We also guarantee that all of the problems are solvable in either C++ or Python. Note that there is at least 1 interactive problem. You should read this guide about interactive problem if you don't know what it is.
All of the problems have been made by Sweet and me.
We would like to thank:
- MikeMirzayanov for incredible and amazing Codeforces and Polygon platforms.
- And we would like to thanks a lot to our teachear, friends, who helped us to become better, and helped us a lot when we made this contest <3.
- Last, but not the least, thank You for participating in our contest <3.
We wish you(if you are still a child like me) best of the luck and to have fun in this special day :3.
UPD: We decided to shift it by one hour, because some participants said that this contest will coincide with the Atcoder Beginner Contest.
UPD2: I and Sweet decided to give you one more hour to solve all of the problems, because of their difficuty.

I’m a little confused- isn’t children’s day on November 14th?
:)) In our country the children day it's June 1
Every country has a different Children's Day, I guess.
1st June is the Vietnamese Children Day.
Ah I see, thanks for the clarification!
Excited for the contest! Could you please shift it by one hour as it is coinciding with the Atcoder Beginner Contest?
Ummm... I will tell that with Sweet again.
:) the contest has been shifted 1 hours
