I find these questions unclearly written. For example, in the license plate case, what does "close" mean? Are 1337 and 1307 close because three digits are exactly the same and the fourth one doesn't matter as long as it's not perfect, or because the nonmatching digit is only 3 away, or because the numbers have a difference of 30 out of a possible difference of thousands, or what?
I meant to say, a close match to what the person said. And I'm not entirely confident that 2 makes sense, I'd like to clarify something but that would give out the answer. Please tell me of the other questions you don't understand.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
