Adjacency matrix and adjacency table storage graph

Graph is a nonlinear table data structure. The elements in the graph are called vertices. A vertex can establish a connection relationship with any other vertex, which is called edge. The number of edges connected to a vertex is called the degree of the vertex. Undirected graph A graph who ...

Graph data structure (4. Graph depth first traversal)

Depth-first traversal of Graphs Presentation Form Starting at a node, walk through the diagram without hitting the South Wall and without looking back.Overall, the depth-first traversal for the number of tuples is similar, but you need a visited data to record whether the node has been visited or not, otherwise a lot of repetitive traversal w ...
