LeetCode ProblemMinimum Degree of a Connected Trio in a Graph
You are given an undirected graph. You are given an integer n which is the number of nodes in the graph and an array edges, where each edges[i] = [ui, vi] indicates that there is an undirected edge between ui and vi. A connected trio is a set of three nodes where there is an edge between every pair of them. The degree of a connected trio is the number of edges where one endpoint is in the trio, and the other is not. Return the minimum degree of a connected trio in the graph, or -1 if the graph has no connected trios.

Understanding the Minimum Degree of a Connected Trio in a Graph Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an undirected graph. You are given an integer n which is the number of nodes in the graph and an array edges, where each edges[i] = [ui, vi] indicates that there is an undirected edge between ui and vi. A connected trio is a set of three nodes where there is an edge between every pair of them. The degree of a connected trio is the number of edges where one endpoint is in the trio, and the other is not. Return the minimum degree of a connected trio in the graph, or -1 if the graph has no connected trios.
