面试题4.1:实现一个函数,检查二叉树是否平衡.在这个问题中,平衡树的定义如下:任意一个结点,其两颗子树的高度差不超过1. 思路:两个方法,第一种速度较快 package cc150; public class Balance { public static void main(String[] args) { // TODO 自动生成的方法存根 } public class TreeNode { int val = 0; TreeNode left = null; TreeNode right…

前一段时间,学习数据结构的各种算法,概念不难理解,只是被C++的指针给弄的犯糊涂,于是用java,web,javascript,分别去实现数据结构的各种算法. 二叉树的遍历,本分享只是以二叉树中的先序遍历为例进行说明,中序遍历和后序遍历,以此类推! 二叉树递归与非递归遍历的区别,虽然递归遍历,跟容易读懂,代码量少,运算快,但是却容易出现溢出的问题,所以所以非递归遍历,在处理千万级的运算量时会先的很有用处. 二叉树的先序遍历:先访问根节点,再访问先后访问左右节点.如图: 二叉树的递归遍历之java…

在这里,邻接表的实现与深度优先遍历图,使用递归. #include<iostream> using namespace std; #define VERTEXNUM 5//结点数 struct edgenode { int to; int weight; // 边的权值 edgenode *next; }; struct vnode { int from; edgenode *first; }; void createGraph(vnode *adjilist, int start, int…

题目: 遍历出aaa文件夹下的文件 首先分析思路: 1.首先判断这个文件夹是否为文件,通过isFile()函数可以判断是否为文件. 2.然后通过isDirectory判断是否为目录. 3.如果是目录就使用递归遍历目录 代码如下: import java.io.File; public class ZuoYe { public static void main(String[] args) { //创建file对象 File f=new File("d://新建文件夹"); //用lis…

题目链接 题目大意:返回二叉树的先序遍历list.中序见94,后序见145. 法一:普通递归遍历,只是这里多了一个list数组,所以分成了两个函数.代码如下(耗时1ms): public List<Integer> preorderTraversal(TreeNode root) { List<Integer> list = new ArrayList<Integer>(); list = dfs(root, list); return list; } public s…
