an edge between node 12 and node 0 with weight 5,
an edge between node 18 and node 0 with weight 2,
an edge between node 2 and node 0 with weight 4,
an edge between node 14 and node 0 with weight 8,
an edge between node 7 and node 1 with weight 3,
an edge between node 10 and node 1 with weight 7,
an edge between node 1 and node 14 with weight 7,
an edge between node 1 and node 6 with weight 10,
an edge between node 17 and node 2 with weight 7,
