Problem Statement

Given a binary tree, your task is to create two functions.

one for serializing the tree into a string format and another for deserializing the string back into the tree.

The serialized string should retain all the tree nodes and their connections, allowing for reconstruction without any loss of data.

Examples

  1. Example 1:
    • Input: [1,2,3,null,null,4,5]
    • Expected Output: [1,2,3,null,null,4,5]
    • Justification: The tree has the structure: 
        1
 / \
2   3
   / \
  4   5
