Can I delete my own question or answer on Stack Overflow?

Yes, you can delete your own question or answer on Stack Overflow. For questions, if your question has answers, you can delete it only if it has zero upvoted or accepted answers. If it has a single upvoted or accepted answer, you cannot delete it. However, if your question has no answers or unvoted answers, you can delete it regardless of the votes. As for answers, you can delete your own answer at any time, irrespective of the votes or question status. Keep in mind that once a question or answer is deleted, it may still be visible to some users with specific privileges or viewable by moderators. Additionally, deleted content may impact your reputation points.
