In a directed graph, the nodes are numbered from 0 to 6, and the edges are: an edge from node 0 to node 3 with capacity 7, an edge from node 0 to node 2 with capacity 4, an edge from node 2 to node 3 with capacity 4, an edge from node 2 to node 6 with capacity 9, an edge from node 3 to node 2 with capacity 6, an edge from node 4 to node 0 with capacity 10, an edge from node 5 to node 2 with capacity 3, an edge from node 5 to node 6 with capacity 3, an edge from node 6 to node 0 with capacity 9.
