题目描述 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. 样例 给出一个测试数据样例, 二叉树{3,9,20,#,#,15,7},表示如下的树结构: 我们的数据是进行BFS遍历得到的.当你测试结果wrong answer时,你可以作为输入调试你的代码.你可以采用其他的方法进行序列化和反序列…

One way to serialize a binary tree is to use pre-oder traversal. When we encounter a non-null node, we record the node's value. If it is a null node, we record using a sentinel value such as #. _9_ / \ 3 2 / \ / \ 4 1 # 6 / \ / \ / \ # # # # # # For…
