Serialize And Deserialize Binary Search Tree (BST) is an example of tree problems. In this post we will see how we can solve in Javascript.

Problem Description

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.

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

Note:

  • The encoded string should be as compact as possible.
  • Do not use class member/global/static variables to store states.
  • Your serialize and deserialize algorithms should be stateless.
