In addition, we are not planning to advertise LGR-219-Div.2, as it is merely a simulation of the Lanqiao Cup provincial competition. Although this competition has 200,000 participants in China, the quality of the problems is relatively average, and code submissions can only be graded after the competition ends. Our mock competition replicates this aspect, so the overall training value of the entire competition might not be very high, and we don't plan to announce it.
Why the contest page shows that only 3.2k people registered?
The Lanqiao Cup has 200,000 participants, but our mock competition certainly won't have that many.
As a problem setter, I really hope this contest will give you a good experience!
As a classmate of the problem setter, I saw your dedication to this contest!
