LeetCode 101 Symmetric Tree 判断一颗二叉树是否是镜像二叉树

Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).For example, this binary tree [1,2,2,3,4,4,3] is symmetric:    1   / \  2   2 / \   / \3  4 4  3 But the following [1,2,2,null,3,null,3] is not:    1   / \ …

101 Symmetric Tree 判断一颗二叉树是否是镜像二叉树

给定一个二叉树,检查它是否是它自己的镜像(即,围绕它的中心对称).例如,这个二叉树 [1,2,2,3,4,4,3] 是对称的.    1   / \  2   2 / \ / \3  4 4  3但是下面这个 [1,2,2,null,3,null,3] 则不是:    1   / \  2   2   \   \   3    3说明:如果你可以递归地和迭代地解决它就奖励你点数.详见:https://leetcode.com/problems/symmetric-tree/description…
