LeetCodeArrayDynamic ProgrammingTreeDepth-First SearchOpen on judge ↗

You are given an undirected tree rooted at node 0, with n nodes numbered from 0 to n - 1. The tree is represented by a 2D integer array edges of length n - 1, where edges[i] = [ui, vi] indicates an edge between nodes ui and vi. You are also given an integer array nums of length n, where nums[i] represents the value at node i, and an integer k. You may perform inversion operations on a subset of
