The meaning of the subject, title. It's easy to understand.The solution is to sort the topology, which can be easily solved.Each input pair of players, to determine whether two players have appeared, did not appear, create a new head node, added to the adjacency table, update the node in the degree.Finally determine if there is a node in the degree of 0, there is, yes, otherwise no.I'm using the list container in the STL to create the adjacency table.The following is the code for the AC:#include

Although Milgram's theory has often been fulfilled, there have been many soci
