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. There is no restriction on how your serialization/deserialization algorithm should work. Flatten Binary Tree to Linked Listĭesign an algorithm to serialize and deserialize a binary tree. Vertical Order Traversal of a Binary Tree Longest Palindrome by Concatenating Two Letter Words Painting a Grid With Three Different Colors One issue in my mind which I cannot resolve is, I am using a global.

The "vaule string" is the values of each node (using preorder order) in string format. The "inorder string" is the indices of each node in inorder order. The "preorder string" is the indices of each node in preorder order, actually, I have given the sequence from 1 to the number of nodes in this string for simplicity. So, our encoding format is: "preorder string inorder string value string". Note that in this problem, there might be duplicate values in different nodes, we have to use the indices of each node for the traversal. Please take a look at my previous post for details. Therefore, we could use preorder and inorder traversal to reconstruct the binary tree. Particularly, we have a binary tree, rather than the level by level traversal, we still have three depth-first traversal: preorder, inorder, and postorder. Although it is not a quite efficient method, it still provides good practice of binary tree and binary tree traversal. Secondly, I'l like to show the implementation using a different way. For the deserialization, we could still keep two queues for the BFS, and keep track of the node we are expanding. Here in my solution, I choose to use two queues, to store nodes in current level, and nodes in next level, respectively. Since we are "searching" the tree level by level, DFS is usually a good way to do so. We will encode the node value level by level, and only encode the "Null" (or "None" in python) node when it is a leaf node. Let's first see the simple way of doing this.
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 computer environment.

Lets have a recap on how to serialize and deserialize a binary tree, Serialization is the process of converting a data structure into a sequence of bits. In this problem, I have implemented a differrent way of serialization (in C++ code shown below).
