General information:
7. For a graph G of order n 2, define the k-connectivity Kk(G) of G (2 S k n) as the minimum number of vertices whose removal from G results in a graph with at least k components or a graph of order less than k. (Therefore, K2(G) = K(G).) A graph G is defined to be (f,k)- connected if Kk(G) . Let G be a graph of order...
