One man has a habit of smoking cigarettes regularly.
But he has a habit of smoking even filters of the cigarette.

An executioner will line up 100 prisoners tomorrow morning.
He will put either a Red or a Blue hat on each prisoner's head.
Every prisoner will see the hats of the people in front of him in the line, but will neither see his own hat, nor will he be able to see the hats of those standing behind him.
The executioner will start from the end of the line (from the last-most prisoner of the row) and will ask him about the color of his hat.
The prisoner will have to answer either "Red" or "Blue".
If he will answers correctly, he will be allowed to live, but if he gives the wrong answer, he will killed instantly and silently.
While everyone else standing in-front of him will hear the answer, no one know whether his answer was right or wrong.
So, on the night before the line-up, all the prisoners came to you for help.
What strategy would you give them that would save the maximum of them tomorrow?
