Hello, programmers! In this tutorial, we will learn Java program for Topological sorting using Kahn’s algorithm. Topological Sorting: The linear ordering of vertices in a Directed Acyclic Graph(DAG) with V vertices and E edges such that every directed edge from vertex u->v, where vertex u comes before v in the order. In-degree: The number of incoming …
