Topological Sort in Graphs
What is Topological Sort?
Topological Sort is a way to order a directed acyclic graph. A directed graph has edges that are incoming or outgoing, meaning that they have a specific direction. An acyclic graph has no cycles, i.e., a node is not reachable from its ancestors. A topological sort takes a graph and finds the order of its nodes so it always starts from a node that has no incoming edges and then traverses the adjacent nodes. Note that the current node is before its adjacent. The illustration below will help explain this concept better.
