Solution: Find Center of Star Graph

Explore how to identify the central node in a star graph by analyzing edge connections. This lesson helps you understand optimized graph algorithms to find the center node quickly, improving your ability to solve graph-related coding interview questions effectively.

We'll cover the following...

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.

Constraints:

  • 3≤3 \leq n ≤103\leq 10^3 ...
