Solution: Find Center of Star Graph
Explore how to find the central node in an undirected star graph by comparing nodes in the first two edges. Understand the optimized O(1) time solution that leverages the star graph's structure to identify the center quickly without counting all degrees.
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...
