Topological Sorting Algorithm

Write a C Program to implement Topological Sorting Algorithm Example. Here’s simple Program to implement Topological Sort Algorithm Example in C Programming Language.

Topological Sorting

Topological sorting or Topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge (u v) from vertex to vertex vu comes before v in the ordering.

For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent constraints that one task must be performed before another; in this application, a topological ordering is just a valid sequence for the tasks.

A topological ordering is possible if and only if the graph has no directed cycles, that is, if it is a directed acyclic graph (DAG).

Any DAG has at least one topological ordering, and algorithms are known for constructing a topological ordering of any DAG in linear time.
