94. Binary Tree Inorder Traversal

[中等] 哈希表


给定一个二叉树的根节点 root ,返回它的 中序 遍历。

 

示例 1:


输入:root = [1,null,2,3]
输出:[1,3,2]


示例 2:


输入:root = []
输出:[]


示例 3:


输入:root = [1]
输出:[1]


示例 4:


输入:root = [1,2]
输出:[2,1]


示例 5:


输入:root = [1,null,2]
输出:[1,2]


 

提示:


	树中节点数目在范围 [0, 100] 内
	-100 <= Node.val <= 100


 

进阶: 递归算法很简单,你可以通过迭代算法完成吗?
