Number of Nodes With Value One: coding question

Available question text

Given a tree (or graph) whose nodes are labeled 0 or 1 and a set of rules/operations that change node values based on ancestors or path flips, determine how many nodes end up with value 1. This typically requires a DFS/BFS that carries a cumulative flip/XOR state (or other propagated state) and careful bookkeeping to apply updates efficiently.
