There are 50 people in the village, and each person has a dog. There is a disease in these 50 dogs (this disease will not be infected). So people will find out the dog. Everyone can observe other 49 dogs to determine if they are sick, only their dogs can't see. The results obtained after observation must not be exchanged, and the owner of the disease dog cannot be notified.
