二叉树的序列化与反序列化. 如果使用string作为媒介来存储,传递序列化结果的话,会给反序列话带来很多不方便. 这里学会了使用 sstream 中的 输入流'istringstream' 和 输出流'ostringstream'. istringstream in; in >> str; 这里没执行一次就会倒出一个string (因为in流中使用了' '空格 作为分割符, 所以可以分成很多个string) 建树的时候使用先序建立二叉树. 关键代码如下: TreeNode* build(ist…

序列化是将一个数据结构或者对象转换为连续的比特位的操作,进而可以将转换后的数据存储在一个文件或者内存中,同时也可以通过网络传输到另一个计算机环境,采取相反方式重构得到原数据.请设计一个算法来实现二叉树的序列化与反序列化.这里不限定你的序列/反序列化算法执行逻辑,你只需要保证一个二叉树可以被序列化为一个字符串并且这个字符串可以被反序列化得到一个原始的树结构.例如,你可以序列化下面的二叉树:    1   / \  2   3     / \    4   5 得到 "[1,2,3,null,nul…

由于一般的前序遍历不能唯一的还原出原本你的二叉树,所以要改变一下: 记录二叉树的结构信息,也就是空节点用符号表示 一般的前序遍历只是记录了节点的前后顺序,通过记录空节点,每一层的结构就可以记录下来 解码的时候可以按照前序的顺序依次还原节点. /* 前序遍历或者层序遍历都可以,前序遍历要保存二叉树的结构信息 空节点用符号表示 */ StringBuilder s = new StringBuilder(); // Encodes a tree to a single string. public…

描述 设计一个算法,并编写代码来序列化和反序列化二叉树.将树写入一个文件被称为“序列化”,读取文件后重建同样的二叉树被称为“反序列化”. 如何反序列化或序列化二叉树是没有限制的,你只需要确保可以将二叉树序列化为一个字符串,并且可以将字符串反序列化为原来的树结构. 对二进制树进行反序列化或序列化的方式没有限制,LintCode将您的serialize输出作为deserialize的输入,它不会检查序列化的结果. 样例 给出一个测试数据样例, 二叉树{3,9,20,#,#,15,7},表示如下的树结…

Given the root to a binary tree, implement serialize(root), which serializes the tree into a string, and deserialize(s), which deserializes the string back into the tree. For example, given the following Node class class Node: def __init__(self, val,…
