Statement

Given an array edges where each element edges[i] = [ui, vi] represents an edge between nodes ui and vi in an undirected star graph,A star graph is a graph where one central node is connected to every other node. If there are n nodes, then the central node must be connected to all other n-1 nodes. find the central node of this star graph.

Note: A star graph is a graph where one central node is connected to every other node. This implies that a star graph with n nodes has exactly n - 1 edges.
