Description

There were various kinds of demons in Binary Forest. They committed terrible crimes. However, no one saw their faces exactly, the only known thing is the height of every kind (demons for the same kind all share a common height, which is different from any other kind). One day, the sheik of the forest asked all men lived in the forest to line up and stand in ascending order of their heights, but he didn't know how to find the demons. Could you please help the poor sheik?
