559. Maximum Depth of N-ary TreeEasy Topics Companies Given a n-ary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Nary-Tree input serialization is represented in their level order traversal...
Given a n-ary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value...
590. N 叉树的后序遍历 - 给定一个 n 叉树的根节点 root ,返回 其节点值的 后序遍历 。 n 叉树 在输入中按层序遍历进行序列化表示,每组子节点由空值 null 分隔(请参见示例)。 示例 1: [https://assets.leetcode.com/uploads/2018/10/12/narytreeexample.png]
[LeetCode] 590. N-ary Tree Postorder Traversal Easy Given an n-ary tree, return thepostordertraversal of its nodes' values. For example, given a3-arytree: Return its postorder traversal as:[5,6,3,2,4,1]. Note: Recursive solution is trivial, could you do it iteratively?
