100 hat puzzle
100 prisoners stand in line, one in front of the other. Each wears either a red hat or a blue hat. Every prisoner can see the hats of the people in front, but not their own hat, or the hats worn by anyone behind. Starting at the back of the line, a prison guard asks each prisoner the color of their hat. If they answer correctly, they will be pardoned. Before lining up, the prisoners confer on a strategy to help them.
What should they do?
