Now that the results are released, let's congratulate all teams that made it to the world finals, and especially those who have won medals and the trophy.

Disclaimer 1: I respect all efforts from judges, and this blog is purely based on my observations and is not intended to be personal. It is not easy to make a problemset and your work is greatly appreciated.

Disclaimer 2: I haven't read the problemset, which means I know nothing about the problems so far. Therefore, feel free to consider this as nonsense.

OK, I only want to emphasize one phenomenon from this contest: Rank 4 (Gold) has the same number of problem solves as Rank 17 (nothing). And what's more, they all solve exactly the same subset of problems.

Last time I saw this, it was in last year's NAC (North America Championship): https://nac.icpc.global/scoreboard/2024/. FYI, Rank 7 has the same number of solves as everyone til Rank 21, with almost the same subset of problems.
