FindThePill

A wise man has committed a capital crime and is to be put to death.
The king decides to see how wise the man is. He gives to the man 12
pills which are identical in size, shape, color, smell, etc. However,
they are not all exactly the same. One of them has a different
weight. The wise man is presented with a balance and informed that all
the pills are deadly poison except for the one which has a different
weight. The wise man can make exactly three weighing and then must
take the pill of his choice.
Remember that the only safe pill has a different weight, but the
wise man doesn't know whether it is heavier or lighter.
