Symmetric Tree -- LeetCode

原题链接: http://oj.leetcode.com/problems/symmetric-tree/ 这道题是树的题目，本质上还是树的遍历。这里无所谓哪种遍历方式，只需要对相应结点进行比较即可。

对称矩阵（Symmetric Matrices）

如果矩阵满足，则矩阵P称为对称矩阵，对称矩阵有很多优秀的属性，可以说是最重要的矩阵。1.对称矩阵的对角化如果一个矩阵有n个线性无关的特征向量，则矩阵是可对角化的，矩阵可表示成，相应的。因为，很有可能A的逆等于A的转置。同样的，就可能有，这可发现S中的特征向量和其他的特征向量正交，后文会进行证明。我们把上的S成为正交矩阵Q，Q满足，Q中的每一个列向量为单位特征向量。每一个对阵矩阵都可以被分解成：2.

错误解法：中序遍历得到的数组是对称的，这是错误的解法比如：1，2，3，3，#，2表示的二叉树是 12 3 3 2中序遍历是对称的，但实际上它不是对称的。正确解法：二叉树是一个对称二叉树的条件：任意二叉树的节点的左右子树都是对称的。T1，T2两棵树是对称的条件：T1，T2根节点相等&& T1.left与T2.right对称&& T1.right与T2.left对称用递归就

!本题分为迭代版和递归版，递归版比较直接，按照树遍历即可。跌代版这里创建了两个队列，每遇到一对节点（初始为根节点的左右子）：1.先对比这两个节点的值是否相等：不相等则结束循环，相等则进入22.把它们的左右子节点，交叉安插到自己的队列中，然后对队列里的front，作为一对节点，走1!iterative1if(!root)returntrue; 2queuequeueStep; 3queueque
