Bipartite Graph from Trees

CodeChefOpen on judge ↗

You are given a rooted tree T with N vertices. The vertices are numbered from 1 to N, and vertex 1 is the root. You are also given M lists A1, A2, .., AM, where each Ai contains a subset of the vertices in T. Consider a new bipartite graph G = (L, R, E), where L = {l1, l2, .., lM} and R = {r1, r2, .., rN} denote the two bi-partitions of the vertex set and E = { (li, rj), such that there exists a
