可复制的六语言 DFS 配置与代码骨架 这一节是全文重点，我会给出 Java、Python、C++、JS、Go、C 六种语言的可复制代码骨架。 所有实现都遵循同一套逻辑：先用哈希表建立「父 ID -> 子 ID 列表」的映射，再从目标 ID 出发用栈做 DFS，最后排序输出。 先看统一的配置片段。

题目要求：给定一棵二叉树的根节点 root，返回其节点值的层序遍历结果，即自顶向下、每一层从左到右，最终输出形如 [[3],[9,20],[15,7]] 的二维数组。 Hint 1 树的「层」指距离根节点相等的一组节点；需要设计一种逐层推进、而不是一路向下的算法 Hint 2 使用 BFS ...
