Answer / daveying99
The problem asks us to figure out a way to let every member of the group of 5 can know the color of every person't hat including himself.
The 5 people are i a circle, looking to the inside of the circle. A person cannot see his own hat color. But he can look around to see the hat colors of the 4 other people.
The following is my solution. The 5 agree before hand to each notice the hat color of the person on their right side. and look directly at another person in the group that has the same hat color that no one is yet looking at.
So for a person to know his own hat color, they must just look at the person on the right of the person who is looking at them. That's the hat color they have. The other 4 people can be seen just by noticing around,
