本文介绍了一种特殊的二叉树遍历方式——螺旋遍历。这种遍历方式按照从左到右，再从右到左的方式逐层访问二叉树节点。通过一个具体的例子展示了如何实现这一遍历过程。

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).
For example: Given binary tree 3,9,20,#,#,15,7,
3
/ \
9 20
/ \
15 7
return its zigzag level order traversal as:
[
[3],
[20,9],
[15,7]
]
题意：
层序遍历的变形。螺旋遍历
