contests I am not here to which extent it is relevant for our site - the question "Given $N$ integers on a circle , what will be the minimum pair sum?" was pointed out to be a part of ongoing contest.

However, the OP has deleted their account, so they cannot undelete it now.

This was pointed out in meta.MO discussion: Rules for deleting one's own question.

@MartinSleziak is the contest over? Generally I'd just leave it deleted. If somebody wants the question on the site they can post it anew.

As far as I can tell, it's not over.

In both cases (MO and MSE) the question was self-deleted. On MSE, the OP cannot undelete it - as they no longer have an account.

On MO I can't see deleted question, but since a mod says that they have deleted it, it probably cannot be undeleted either.

@Martin maybe I am slow today, but I don't understand the concern. Who cannot undelete it?

The OP cannot undelete it.

There are no really important concerns about this question.

Anyway, since a contest question post on MSE was mentioned at the meta.MO discussion, I've mentioned the question also here.

Just in case. It seems unlikely that something is going to happen.

As I have mentioned, the OP of the MSE question no longer has an account - so they cannot undelete it. And I doubt that the poster of the only answer is going to request undeleting.

THanks for the clarification.
