"WebNov 7, 2024 · 14. 4.1.1. Depth-first solution ¶. A topological sort may be found by performing a DFS on the graph. When a vertex is visited, no action is taken (i.e., function PreVisit does nothing). When the recursion pops back to that vertex, function PostVisit prints the vertex. This yields a topological sort in reverse order. " - Dfs based topological sort
