In a directed graph, the nodes are numbered from 0 to 4, and the edges are:
an edge from node 0 to node 1 with capacity 1,
an edge from node 0 to node 2 with capacity 9,
an edge from node 1 to node 3 with capacity 6,
an edge from node 1 to node 4 with capacity 2,
an edge from node 1 to node 0 with capacity 1,
an edge from node 1 to node 2 with capacity 3,
an edge from node 3 to node 0 with capacity 1,
an edge from node 4 to node 0 with capacity 3.
