    297 - Serialize and Deserialize Binary Tree\.

    Hard

    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 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.

    Clarification: The input/output format is the same as how LeetCode serializes a binary tree. You do not necessarily need to follow this format, so please be creative and come up with different approaches yourself.

    Example 1:

    Input: root = 1,2,3,null,null,4,5

    Output: 1,2,3,null,null,4,5

    Example 2:

    Input: root = []

    Output: []

    Constraints:

    • The number of nodes in the tree is in the range <code>0, 10<sup>4</sup></code>.

    • -1000 &lt;= Node.val &lt;= 1000
