Why was my question Is the Frog game solvable in the root of a full binary tree? deleted?
It was a cross-post, but I followed all recommended advices when doing so.
It was also decently upvoted (12+).
It was fine for 2 years, but now it is suddenly deleted.
I'm really confused.
I wanted to suggest undeletion, but it says it was deleted by a moderator.
