The multi-line adjacency list format is useful for graphs with nodes that can be meaningfully represented as strings. With this format simple edge data can be stored but node or graph data is not. Format ------ The first label in a line is the source node label followed by the node degree d. The next d lines are target node labels and optional edge data. That pattern repeats for all nodes in the graph. The graph with edges a-b, a-c, d-e can be represented as the following adjacency list (anything following the # in a line is a comment):: # example.multiline-adjlist a 2 b c d 1 e )generate_multiline_adjlistwrite_multiline_adjlistparse_multiline_adjlistread_multiline_adjlistN) open_filec ## UR5(GaZUR5(aUR5Hup#UR5VVVVs/sH"upEUR5HupgXG4PM M$ nnnnn[ U5n [ U5U-[ U 5-v UH3upJU c[ U5v M[ U5U-[ U 5-v M5 M gUR5Hsup#[ U5n [ U5U-[ U 5-v UR5H3upJU c[ U5v M[ U5U-[ U 5-v M5 Mu gUR5(a[ 5n UR5Hup#UR5VVVVs/sH)upEXK;dM UR5HupgXG4PM M+ nnnnn[ U5n [ U5U-[ U 5-v UH3upJU c[ U5v M[ U5U-[ U 5-v M5 U RU5 M g[ 5n UR5Hup#UR5VV s/sHupJXK;dM XJ4PM nnn [ U5n [ U5U-[ U 5-v UH3upJU c[ U5v M[ U5U-[ U 5-v M5 U RU5 M gs snnnnfs snnnnfs sn nf7f)aGenerate a single line of the graph G in multiline adjacency list format.
