Problem description:

Both Xiao Wang and Xiao Li have sufficient reasoning ability. On this day, they are being interviewed by reasoning. They know that there are the following 16 playing cards in the desk drawer:

Hearts a, q, 4

J of spades, 8, 4, 2, 7, 3

Caohua k, q, 5, 4, 6

A, block 5

Professor Zhang draws a card from 16, tells Xiao Wang the number of points in this card and tells Xiao Li the color of this card. At this time, Professor John asked Xiao Wang and Xiao Li if you could infer what this card was from the known points or colors.

Xiao Wang said, I don't know this card.

Xiao Li said, I know you don't know this card.

Xiao Wang: Now I know this card.

Xiao Li: I know that too.

Excuse me, what card is this?

Why?

Analysis:

Box 5

1, Xiao Wang: \ "I don't know this card. \"

This means that this is a card with repeated points. Actually, this is all bullshit. If I knew, I wouldn't have this problem.

2. Xiao Li: \ "I know you don't know this card. \"

Xiao Li knows the color and is sure that A can't get this card directly. Possibility:

Definitely 1- red hearts are repeated points.

2- Not sure if spades have a unique point.

3- Grass flowers are not necessarily without duplication.

All four squares are positive repetitions.

Feedback to Xiao Wang: The color is hearts or diamonds.

3. Xiao Wang: \ "Now I know this card. \"

Judging from the above information, the remaining cards are:

Hearts a, q, 4

A, block 5

I know which card it is by counting, which means it can't be counted as one.

The remaining cards fed back to Xiao Li are:

Q, four of hearts

Box 5

4. Xiao Li: "I know that, too. \"

It shows that Xiao knows which card to judge from the news and suit.

Feedback to me: the card is 5 diamonds.
