Let G be an undirected graph whose vertices are the integers 1 through 8, and let the adjacent vertices of each vertex be given by the table below: Vertex Adjacent Vertices 1 (2, 3, 8) 2 (1, 3, 4)  3 (1, 2, 4) 4 (2, 3, 6) 5 (6, 7, 8) 6 (4, 5, 7) 7 (5, 6, 8) 8 (1, 5, 7) Assume that, in a traversal of G, the adjacent vertices of a given vertex are returned in the same order as they are listed in the table above. Give the sequence of vertices of G visited using a BFS traversal starting at vertex 1.
