Prove that G is connected.
(b) Examine the sharpness of the bound in (a).
2- Prove the every graph G has a path of length .( min ...
Prove that a graph G is connected - 1.20 Prove that a graph G is connected if and only if for every partition
V(G)=V_1 U V_2 (means V_1 union V_2), there exists an edge of G joining a vertex of V_1 and a vertex of V_2.
