最近实验室师兄找工作,今天帮师兄做了一道亚马逊中国的在线笔试题。说的是Symmetric Number(对称数字),即给定一个数字,获取大于它且最接近它的对称数字。 例如,123对应131,12321对应12421。正常要求是C语言实现,可惜本人习惯于JAVA,所以用JAVA写了一段代码,测试通过。代码如下: public class SymmNum {pu

题目: Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).For example, this binary tree is symmetric:1/ \2 2/ \ / \3 4 4 3But the following is not:1/ \2
Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center). 给定一颗二叉树,判断该二叉树是否是对称的。 For example, this binary tree is symmetric: 如下面的二叉树是对称的。 1/ \2 2/ \3

题目描述 Given a string, you are supposed to output the length of the longestsymmetric sub-string. For example, given "Is PAT&TAPsymmetric?", the longest symmetric sub-string is "sPAT&TAP s", hence
题目: 给定一个二叉树,检查它是否是镜像对称的。 Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center). 例如,二叉树 [1,2,2,3,4,4,3] 是对称的。 For example, this binary tree [1,2,2,3,4,4,3] is s
Symmetric Tree 这个题说难不难,第一思路还是广度优先遍历,广度优先遍历需要一个数据结构去存储下次需要遍历的节点,加上这题的要求,可以选择申请两个数据结构,一个专门存左节点一个专门存右节点,代码稍微乱了点,但是思路简单 /*** Definition for a binary tree node.* struct TreeNode {* int val;* Tree
