Struct2Vec Lite

Problem

Rank nodes by structural similarity to a target using degree difference as a lightweight proxy.

Return all other nodes ordered by increasing absolute degree difference to the target, breaking ties by smallest index. edges is a list of [u, v] pairs and node is the target.

Hint

Struct2Vec captures structural identity rather than proximity in the graph.

Test cases

case 1

in: [5,[[0,1],[0,2],[1,2],[2,3]],0]

expected: [1,2,3,4]

case 2

in: [4,[[0,1],[1,2],[2,3]],1]

expected: [2,0,3]

case 3

in: [3,[[0,1],[1,2]],0]

expected: [2,1]
