But it needs to be ensured that the serialised binary tree can be deserialized to the original tree structure. Serialisation 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.

Serializing a Binary Tree in Python This can be done using the depth-first traversal methods - preorder, inorder, and postorder. Of these, the preorder traversal is the easiest to serialize and deserialize because it enumerates the current node before its child nodes.

When you want to have a richer interaction, you need to use Expression Trees. Expression Trees represent code as a structure that you examine, modify, or execute. These tools give you the power to manipulate code during run time. You write code that examines running algorithms, or injects new capabilities.
