Consider that we have an acyclic directed graph whose edges include

Consider that we have an acyclic directed graph whose edges include (1,5) and (5,7). Answer each of the following about a Depth-First Search of this graph starting from node 1. Q2.1 1 Point Which must be true of the order in which nodes 5 and 7 are marked as "done"? 7 must be "done" before 5 . 5 must be "done" before 7 . 5 and 7 might be "done" in either order (depending on the other edges in the graph and the implementation details of the DFS). Q2.2 1 Point Which must be true of the order in which nodes 5 and 7 are marked as "seen"? 7 must be "seen" before 5 . 5 must be "seen" before 7. 5 and 7 might be "seen" in either order (depending on the other edges in the graph and the implementation details of the DFS)
