Topological Sorting
Topological Sorting is the process in which the main goal is to find an ordering of vertices in a directed acyclic graph (DAG) that places vertex u before vertex v for any directed edge (u, v). “Topological order” is the name given to this linear arrangement. If a DAG contains cycles, it might not have any topological ordering at all.
For example, a topological sorting of the following graph is “5 4 2 3 1 0”. There can be more than one topological sorting for a graph. Another topological sorting of the following graph is “4 5 2 3 1 0”. The first vertex in topological sorting is always a vertex with an in-degree of 0 (a vertex with no incoming edges).
C Program for Topological Sorting
A fundamental procedure in computer science called topological sorting is used to arrange the nodes in a directed network. This sorting method makes sure that vertex u is placed before vertex v in the sorted order for each directed edge (u, v). Numerous fields, including work scheduling, project planning, and dependency resolution, use topological sorting extensively.
