Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another comput…

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…

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…
