3600. Maximize Spanning Tree Stability with Upgrades

LeetCodeBinary SearchGreedyUnion-FindGraph TheoryMinimum Spanning TreeOpen on judge ↗

You are given an integer n, representing n nodes numbered from 0 to n - 1 and a list of edges, where edges[i] = [ui, vi, si, musti]: - ui and vi indicates an undirected edge between nodes ui and vi. - si is the strength of the edge. - musti is an integer (0 or 1). If musti == 1, the edge must be included in the spanning tree. These edges cannot be upgraded. You are also given an integer k, the
