In this Leetcode problem, we are given a list of edges representing a star graph. A star graph is a graph where all the edges contain the “center” node. This is the problem statement:
There is an undirected star graph consisting of
nnodes labeled from
n. A star graph is a graph where there is one center node and exactly
n - 1edges that connect the center node with every other node.
You are given a 2D integer array
edges[i] = [ui, vi]indicates that there is an edge between the nodes
vi. Return the center…
