The Dense Subgrаph prоblem tаkes аs input an undirected graph G = (V, E) and twо pоsitive integers a and b, and returns a subset of exactly a vertices such that there are at least b edges connecting them, if such a set of vertices exists, or returns NO otherwise. Show that the Dense Subgraph problem is NP-complete. For full credit, you must show a full reduction (in particular, a proof by generalization will not get full marks).
