Binary Tree Zigzag Level Order Traversal问题及解法
问题描述： Given a binary tree, return the zigzag level order traversal of its nodes' values. (ie, from left to right, then right to left for the next level and alternate between). 示例： Given binary t
Leetcode 103 Binary Tree Zigzag Level Order Traversal（BFS）
题目连接：Leetcode 103 Binary Tree Zigzag Level Order Traversal 解题思路：与Leetcode 102 一样，使用BFS层次遍历二叉树，不同的是，对于奇数层，要翻转一下结点顺序。 /*** Definition for a binary tree node.* struct TreeNode {* int val;* Tree

LeetCode_103. Binary Tree Zigzag Level Order Traversal
LeetCode_103 Binary Tree Zigzag Level Order Traversal 给定一个二叉树，返回其节点值的锯齿形层次遍历。（即先从左往右，再从右往左进行下一层遍历，以此类推，层与层之间交替进行）。 例如： 给定二叉树 [3,9,20,null,null,15,7] 返回锯齿形层次遍历如下： [ [3], [20,9], [15,7] ] 思
