I got stuck on cheese counting:

inventory.count(cheeseName) == 1 ? "Yes" : "No"

1 cheese == some, 2 cheese == none :/

Yeah, that's confusing to read. A hashset can only contain at most one of each cheese kind, in c++20 you can write inventory.contains(cheeseName), before that you had to use .count or inventory.find(cheeseName) != inventory.end() or something like that
