Unformatted text preview: cp, its adjacency matrix becomes that of 92. [ ~ 1 0 n (c) [BB] P = o 0 o 0 0 1 (d) [BB] The digraphs are strongly connected: In 91, for instance, VI V2V3 V4 VI is a circuit which respects arrows and 92 is isomorphic to 91 hence, also strongly connected. (e) [BB] The digraphs are not Eulerian. In 910 for instance, vertex V2 has indegree 2 but outdegree 1. 15.
