WebFeb 16, 2024 · 1. Basically, there are two algorithms used for topological sort, described on Wikipedia. Kahn's algorithm works with any graph traversal, including BFS or DFS. Tarjan's algorithm, which is now the most well known, uses a "reverse DFS postorder" traversal of the graph. Postorder means you add a node to the list after visiting its children. WebJul 24, 2024 · Topological Sort – Code GFG– Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge uv, vertex u comes before v in the ordering. Topological Sorting for a graph is not possible if the graph is not a DAG. The first vertex in topological sorting is always a vertex with in-degree as 0 (a …
