Graph topological order

WebA Topological sort or Topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. Topological order is possible if and only if the graph has no directed cycles, i.e. if the graph is DAG. For example, consider the following graph: WebTopological Sort: A topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u …
