(12p) Topological sorting for a DAG is a linear ordering of vertices such that for every directed edge (u,v). vertex u is listed before v in the ordering. Topological Sorting for G is not possible if G is not a DAG. Topological sorting is useful, for example, for scheduling a set of tasks (nodes) into a sequential order, where there are prerequisite-condition relations (directed edges) among some pairs of tasks. Design a polynomial time algorithm that performs the topological sorting for any given DAG
