Inside you are two wolves. Inside each wolf are two more wolves, recursively. You have received advice from a bread-carrying passerby about a house ahead with infinite rooms. Each room is occupied by a grandma. Each grandma has a semaphore with capacity to receive bread twice or be eaten at most once. Propose an algorithm for your wolves to exit the containment structure and consume half of the grandmas before the passerby fills half of them with bread. Describe its execution characteristics.
