From 2 to 100, there are 99 numbers, and two numbers have been drawn, and these two numbers tell A, and they tell B. The following is a conversation of these two: A: I don't know which two numbers, but I am sure you don't know. After era, I heard it slightly, say: I didn't know which two numbers were it, but now I know. After listening, first, then do it, say: Oh, I also know. Excuse me: Which two numbers are extracted?
