Kahn's algorithm works with any graph traversal, including BFS or DFS. … WebJun 16, 2024 · Topological Sorting. The topological sorting for a directed acyclic graph is the linear ordering of vertices. For every edge U-V of a directed graph, the vertex u will come before vertex v in the ordering. As we know that the source vertex will come after the destination vertex, so we need to use a stack to store previous elements.

WebFeb 23, 2024 · According to Introduction to Algorithms, given a directed acyclic graph (DAG), a topological sort is a linear ordering of all vertices such that for any edge (u, v), u comes before v. Another way to describe it is that when you put all vertices horizontally on a line, all of the edges are pointing from left to right.
