In case of not unique answer one must output one with smallest number of line with mistake.
Test #4 is the first with non-unique answer.

No, checker works almost correctly: the only case when it does not accept correct answer is when financial error can be corrected by changing the last number in a sequence...
I fixed the checker. Rejudge started.

It contained more than one error!
New version is already in use, and waiting for rejudge.

Problem will be rejudged in evening.
