Serialize and Deserialize Binary Tree Problem Statement Design an algorithm to serialize and deserialize a binary tree. There is no restriction on how the serialization and deserialization takes place, but it must be ensured that a serialized binary tree can be deserialized back to its original tree structure. Serialization is the process of translating a data structure or object state into a format that can be stored or transmitted (for example, across a computer network) and reconstructed later. The opposite operation, extracting a data structure from stored information, is deserialization. Input Format The input will be a binary tree structure. Output Format Your serialization function should return a string representation of the tree. Your deserialization function should reconstruct the original binary tree from the given string. Examples Example 1: Input: Binary Tree: 1 2 3 1 1 4 5 (representing the tree: 1 left: 2, right: 3; 3 left: 4, right: 5; 1 denotes a null child) Output: After Serialization: 1,2,3, , ,4,5, , , , , After Deserialization: (Original Tree Back) Example 2: Input: Binary Tree: 1 2 3 1 4 5 1 (representing the tree: 1 left: 2, right: 3; 2 right: 4; 3 left: 5; 1 denotes a null child) Output: After Serialization: 1,2,3, ,4,5, , , , After Deserialization: (Original Tree Back)
