Find the star vertex

- You are given a graph that consists of $N$ nodes labeled from $1$ to $N$. A star graph is a graph where there is one center node and exactly $N-1$ edges that connect the center node with every other node. - Your task is to implement a function “isCenterOfStarGraph(edges, node)” that takes a list of edges representing the graph and a node as input and returns true if the given node is the center
