New Brain Teaser
An interesting one...
Five prisoners are going to take beans from a bag with 100 beans. They will do
it one prisoner at a time, and only once each. No communication is allowed
between them, but they can count the beans left in the bag. All prisoners who
end with the largest and the smallest number of beans will die.
Who is most likely to survive?
Assume:
1. they are all smart people.
2. their first priority is to survive, second priority is to kill other prisoners.
3. they do not need to take out all the 100 beans.
