ISBIAS Jan Long Ambigous

Equality (ISBIAS) was really ambiguous and even the testcases were weak.
Even certain wrong solutions passed.

I hope you read in constraints A1,A2,…,AN are pairwise distinct.

Yes I found it ambiguous too at first. But logic for the solution made it clear.

Yes i agree but the wrong logic was getting AC

Examples please!

Im sorry … i had the question misinterpreted … sorry to take up your time
