Test instructions: A set (matrix) m[i][j]=m[j][i] weight, divided into two sets, so that its weight value is maximum. Note: Weights in the same set can only be counted one.Idea: DFS Assume that all are in the collection 0 Get the collection 1 when you traverse the ID. If the overall weight of the set 0 associated with the ID is to be added, the overall weight value should be reduced If you get a set of 1 weights, go back to

First, the basic elements of the diagram1. Vertex/node (vertex);2. Edge (Edge), connecting two points, can be without direction can also be for the edge, you can for the right side can also be the right side;3. Connected graph: Any two points on the diagram are connected. That is, any two points are connected by one or more edges.4. Connected components: Maximum connected subgraph. That is ① is the subgraph of the graph; ② the subgraph is connected; ③ is the subgraph with the largest number of n
