2497. Maximum Star Sum of a Graph There is an undirected graph consisting of n nodes numbered from 0 to n - 1. You are given a 0-indexed integer array vals of length n where vals[i] denotes the value of the ith node. You are also given a 2D integer array edges where edges[i] = [ai, bi] denotes that there exists an undirected edge connecting nodes ai and bi. A star graph is a subgraph of the given graph having a center node containing 0 or more neighbors. In other words, it is a subset of edges ...
