![(1) T F Given a directed graph G and a vertex v in the graph, breath first
search (BFS) can be used to detect if v is part of a cycle in the graph.
(2) T F Let P be a shortest path from some vertex s to some other vertex t in
a directed graph. If the weight of each edge in the graph is decreased by one,
then P will still be a shortest path from s to t.
(3) T F

Kruskal's algorithm is always correct even in graphs with negative
weights.
(4) T F
For any flow network, there is only one unique way to assign flow
value to the edges so as to achieve the maximum flow for the network.
