Candy Game (Equalization)
Kids in a circle share candy each round. Does it ever equalize?
by MindYourPuzzle
Students sit in a circle with an even number of candies each. On each whistle: everyone passes half their candies left. Anyone with an odd count gets +1 from the teacher.
Prove students eventually all have equal candies.
