topological ordering of a direction graph This article is from "Data Structure and algorithm" (C language Edition) (third edition), the publishing house is Tsinghua University Press. This blog post is organized as a learning material. The source code is VC + + 6.0 executable program, I moved to the VS2010 in the implementation. New C + + WIN32 console Application project in VS2010 to create a screenshot of the results: The basic idea of topological ordering of a direction graph is to select

A complex project can often be broken down into a set of small tasks, and accomplishing these tasks means completing the entire project. For example, automotive assembly engineering can be broken down into the following tasks: Putting the chassis on the assembly line, loading the shaft, seating the seat on the chassis, painting, loading the brakes, loading doors and so on.

sufficient to form a tree-containing (n-1) edge. The storage structure of the graph:--array representation/matrix;--adjacency table: a single linked list with each vertex as the head node;--The Cross linked list: The graph, adjacency table plus inverse adjacency table; a node contains two linked lists of adjacency table and inverse adjacency table;--adjacency multiple tables: Similar to the cross list, each node represents the information of the Edge, Stores information about the next related s
