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 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.

The tree is represented as a level-order list. Implement two functions:

- serialize(root: list) -> str that converts the tree to a string.

- deserialize(data: str) -> list that converts the string back to the tree.

For testing, implement serializeDeserialize(root: list) -> list that serializes and then deserializes, returning the result.
