Solution: Find Center of Star Graph
Understand how to find the center of a star graph by leveraging the unique structure where one node connects to all others. This lesson helps you implement an optimal O(1) time solution by comparing nodes in the first two edges, providing a clear algorithmic strategy for graph problems.
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,
Note: A star graph is a graph where one central node is connected to every other node. This implies that a star graph with
nnodes has exactlyn - 1edges.
Constraints:
n...
