Transmission DoorAlgorithm training Shortest time limit: 1.0s memory limit: 256.0MB 1 brocade sac 2 Jin sac 3 problem descriptionGiven an n vertex, the forward graph of the M-Edge (some of which may be negative, but no negative ring is guaranteed).

Traversal of graphs Graph traversal (traversing graph): from one vertex of the graph, visit the remaining vertices in the diagram, and each vertex is only accessed once.The traversal algorithm of graphs is the basis of operation of various graphs.

  Both the Spanning Tree and the least spanning tree are in the undirected graph. Spanning Tree: contains n nodes of a connected graph and n-1 edges. A connected graph can have multiple spanning trees. Minimum Spanning Tree: it is a weighted
