I was trying to solve this question, and I think I made fairly decent progress on it. However, the OP deleted the question despite them putting a lot of work into it.
Is there a way to flag a deleted answer and for a moderator to reopen it? This question might have been answered before, but I have never come across this situation before and I have tried searching on Meta on what to do. Feel free to downvote if you disagree, but I find it somewhat insensitive for someone to delete their question without knowing there could be someone out there who made quite a bit of progress on it.
I have tried using the Help Center, but there does not seem to be an option that could help in this situation other than selecting "other".
