Understanding the Find Center of Star Graph Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
There is an undirected star graph consisting of n nodes labeled from 1 to n. A star graph is a graph where there is one center node and exactly n - 1 edges that connect the center node with every other node. You are given a 2D integer array edges where each edges[i] = [ui, vi] indicates that there is an edge between the nodes ui and vi. Return the center of the given star graph.

Examples
edges = [[1,2],[2,3],[4,2]]2As shown in the figure above, node 2 is connected to every other node, so 2 is the center.
edges = [[1,2],[5,1],[1,3],[1,4]]1Constraints
3 <= n <= 105edges.length == n - 1edges[i].length == 21 <= ui, vi <= nui != viThe given edges represent a valid star graph.How Interview Coder Helps with Leetcode Problems
