The below question refers to shortest paths trees in weighted, directed graphs. Read the following carefully. Assume that No two edges have the same weight There are no cycles of net negative weight. There are no self-edges (edges leading from a vertex to itself). There are V vertices and E edges. 1. Assume that in addition to the conditions specified at the beginning, graphs are dense. If a graph contains V vertices and E edges, what is the greatest number...

Let G = (V, E) be a directed acyclic graph with n vertices and m edges. Give an O(n + m) time algorithm that determines if G contains a directed path that touches every vertex in G exactly once. The graph G is given by its adjacency list representation.
question 1 and 2 please, thank
you.
1. In the following graph, suppose that the vertices A, B, C, D, E, and F represent towns, and the edges between those vertices represent roads. And suppose that you want to start traveling from town A, pass through each town exactly once, and then end at town F. List all the different paths that you could take Hin: For instance, one of the paths is A, B, C, E, D, F. (These...
