Solution: Find Center of Star Graph
Let's solve the Find Center of Star Graph problem using the Graphs pattern.
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
n
nodes has exactlyn - 1
edges.
Constraints:
n
edges.length
n - 1
edges[i].length
ui
,vi
n
ui
vi
The given edges represent a valid star graph.
