Wrong soln for C2.Disgusting + GCD (Checker Version) in Codeforces Round 1132 (Div. 2) got accepted

Revision en1, by L_ryuzaki_, 2026-11-10 23:30:43

A wrong solution to C2 got accepted: https://codeforces.me/contest/2284/submission/397621024

I submitted the exact same code initially and received a WA. However, when I submitted it again, without making any changes, it got accepted.

I understand that an incorrect solution might pass due to gaps in test coverage, but this raises a concern about the reliability of the judging system. It doesn't seem fair in competitive programming when the same incorrect code can receive different verdicts on separate submissions.

Shouldn't identical submissions produce consistent verdicts under the same judging conditions?
