Topological sort of a DAG is a linear ordering of the DAG's vertices in which each vertex comes before all vertices to which it has outbound edges. Every DAG has at least one but possibly more topological sorts/ordering. One of the main purpose of (at least one) topological sort of a DAG is for Dynamic Programming (DP) technique.
