In a network of weather stations, each station is required to know how many hours of daylight there were at each of the others. Unfortunately their email system has been infected by a virus and they can only communicate via phone calls. For three stations, show that three separate calls are required so that all three sets of results are known at all three stations. For five stations show that at least six separate calls are required what is the minimum number of calls if there are seven stations? extend your reasoning for n stations.
