Design an algorithm to serialize and deserialize a binary tree. There is no restriction on how your serialization/deserialization algorithm should work. You just need to ensure that a binary tree can be serialized to a string and this string can be deserialized to the original tree structure. Fo...

对于上面这棵树,这种方法会把它serialize成"1,2,X,X,3,4,X,X,5,X,X,"这样的字符串。也就是preorder地遍历。buildTree的过程也是递归,跟serialize的过程其实就是相反的。递归构造一棵树的方法还是值得注意的。 privatestaticfinal String spliter=",";privatestaticfinal String NN="X";// Encodes a tree...
Note: Do not use class member/global/static variables to store states. Your serialize and deserialize algorithms should be stateless. 解答: public class Codec { private String spliter = ","; //用一个特殊的符号来表示null的情况 private String NN = "X"; ...
Note: Do not use class member/global/static variables to store states. Your serialize and deserialize algorithms should be stateless. 设计一个方法将一个二叉树序列化并反序列化。序列化是指将对象转化成一个字符串,该字符串可以在网络上传输,并且到达目的地后可以通过反序列化恢复成原来的对象。
297. Serialize and Deserialize Binary Tree 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...
