By accident,I found that submission to unfinished round is feasible actually.

At Feb/14/2024 18:00(UTC+8),I submitted my code to round 925(div.3) 's test from other website — the luogu,and it successed.(though failed to past the test,sad. qwq)

But I realized that this round haven't fully finished at all.

Hope this error could be fixed, and thx for codeforces!
