Let G=(V,E) be a digraph and let Vr be the set of the scc’s (strongly connected components) of G. Define a function f: V —> Vr such that for any v in V, f(v) is the accused to which v belongs. If G has no self-loops and is such that f is injective, then G is a DAG. Prove or disprove. Show all your work and complete the proof or disprove it with counterexamples.
