It is worth noting that when the graph is not acyclic, topological_sort result would still be somewhat meaningful in a sense that if a vertex u is reachable from vertex v , but not vice versa, the vertex v will always come first in the resulting array. ...
How to implement topological sort ? I think that the easiest way is to add to Queue vertives, which have zero in-degree. Loop Get vertex from queue ( let's say it is vertex v) and add to result list Decrement all in-degree of neighbours of v. If a neighbour will have in-degree...

Some of the applications of topological sort are:Task Scheduling: Used to schedule tasks based on dependencies. Each task is a node, and dependencies are edges. This ensures tasks are executed in the correct order. Course Prerequisites: Helps in deciding the order of taking courses. Courses are...
However, it is often the case that a small amount of overhead yields dramatic improvements in the asymptotic complexity of the algorithm.doi:10.1007/978-1-4612-4400-4_2Dexter C. KozenSpringer New York
In subject area: Computer Science A topological sort is a linear ordering of vertices in a directed acyclic graph (DAG) where each vertex appears after its predecessors. It is used to show the precedence among events and is especially useful in modeling input-output relationships of combinational...
