Challenge 1


A friend of yours is the director of a zoo. She has described you the latest acquisition she was considering for her zoo: a rare colony of chameleons. This colony of chameleons includes 34 red, 35 blue, and 30 green individuals. Whenever two chameleons of different colors meet, each changes to the third color. The color mutation is a unique feature an your friend expects to attract many visitors with this colony. Still, the director considers: if, by any chance, all 99 chameleons are in the same color, the colony will stop being an attraction.
