    I don't think you should post this until APIO results are in public (after 10/5). There is a chance that the official results may differ from what the students reported.

      This entire list consists of unofficial reports made prior to any press release (save for the Japanese and the Chinese). There is a chance that it will differ, but everything in this list is. Thus, I will not retract this notification unless otherwise stated

Nothing but love to the Iranian people, but if you're gonna ban Israel then you 100% should ban Iran lol. The islamist government literally killed 1500 civilians straight up. Does the IOI committee not care about civilians being murdered?

let us have something to see now

Problem 3 (Tilling, Day 1) in Luogu is a "Yellow Problem" (About CF*1200)

But Problem 1 (Ballmachine, Day 1) in Luogu is a "Black Problem" (More than CF*3500, Chinese Means "More than NOI or CTS")

That is not all, Player Phuc Nguyen Khanh, Vietnam, is the first player get 100 points of Ballmachine,

but only gets 16 points of Tilling.

Fine, that is a pity.
