Pergunta 1
Problem Analysis:
A k-star consists of a center node and up to k arms (edges to other nodes)
We need to find the k-star with maximum sum of all its nodes
For each potential center, we choose the best neighbors (up to k) to maximize sum
Algorithm:
Build an adjacency list from the edges
For each node as a potential center:
Get all its neighbors
Sort neighbors by their values (descending)
Select up to k best neighbors
Calculate sum: center + selected neighbors
Return the maximum sum found

the first step is a leetcode like challenge, easy to medium difficulties. for 2 hour, there is enough time for you to solve them. if you pass the test cases, the following is the video math OA
