Hello, Codeforces!

We are excited to invite you to participate in Game of Coders 5.0 | Finals Round Mirror!

Game of Coders is a contest organized by the ICPC Mansoura Community. The original contest is being held in Mansoura, Egypt, as preparation for the upcoming ECPC competition.

The mirror contest will begin on July 25, 2026 at 10:35 UTC+3.

You will have 5 hours to solve 15 problems. The contest follows the ICPC format, and the problems are not sorted by difficulty, so make sure to read the entire problem set carefully!

We hope the contest provides useful practice for teams preparing for ECPC, while still being an enjoyable challenge for everyone else.

Hi, I wanted to share something weird that happened to me in the previous round.

After about an hour, I submitted this code for problem D: Submission 306394465

I knew the code had high memory and time complexity, but I was confident it would pass given the constraints. However, I received a Memory Limit Exceeded (MLE) verdict.

After the round, I resubmitted the exact same code using C++ 17, and it passed—with a huge difference in memory usage!

I just wanted to share this random incident and ask if anyone knows the reason behind it.
