LINKEDIN interview question

Serialization is the process of converting a data structure or object into a sequence of bits for storage or transmission, allowing for reconstruction later.

Design an algorithm to serialize and deserialize a binary tree. The goal is to convert a binary tree into a string and then reconstruct the original tree from that string.

Note: While the input/output format should resemble how LeetCode serializes a binary tree, you are encouraged to explore different approaches.

Start with the linked LeetCode problem to review the expected serialization and deserialization behavior for binary trees. Done means converting a binary tree to a string and reconstructing an equivalent tree, with input and output resembling LeetCode's format.
