I am a fan of online literature. According to the knowledge I have learned, I will answer the following questions:
Here are some funny IQ questions:
There are four people in a room but only three playing cards. Can they win the game by playing poker?
Answer: Yes, because they can use cards of any color to form any combination.

There was a man who had a sword but had no opponent. Who was he?
Answer: He could be Dumbledore, the character in the Harry Potter movie, the Headmaster of Hogwarts.
The following are all interesting problems:
Grandfather's Paragon: A philosopher who studied time travel proposed a contradiction. He believed that if time travel was possible, a person could go back in time and kill his grandfather to avoid being born. But if he killed his grandfather, he would not be born, so time travel itself became a contradiction.
The Barber's Paragon: This Paragon originated from a town where there was only one hairdresser. He told the townspeople that if he didn't cut his hair, he wouldn't be a hairdresser anymore, so he had to cut his hair. But if he cuts his hair, then he is no longer a hairdresser, so he must not cut his hair. This contradiction showed that the self-contradiction of some assumptions could lead to logical confusion.
3 Infinite Monkey Theorems: This theorem states that if a monkey presses a key an infinite number of times in an infinite monkey experiment, it will produce a complete work of William shakespeare. This contradiction showed that in some cases, the infinite possibilities of logic could lead to the wrong result.
4 Grandfather Paragon: This is similar to the Grandfather Paragon but it involves two grandfathers. If a person could go back in time and kill his grandfather, then he would not be born, so his other grandfather must die, but because his other grandfather was dead, he could not be born, so he must kill his own grandfather. This contradiction showed that the self-contradiction of some assumptions could lead to logical confusion.
