Feature #7: Serialize and Deserialize File System

Implement the "Serialize and Deserialize File System" feature for our "Operating System" project.

Description

We want to make a remote sync utility for our OS that will allow us to copy a portion of the filesystem, rooted at a specific directory, to a distant machine. Therefore, the first step will be to create the same hierarchical directory structure on the remote machine. Our entire filesystem will be present in memory as an N-ary tree. We will use serialization to convert and store the N-ary tree into a string. This will save the state of the filesystem. We can recreate the N-ary tree when needed, using deserialization.

We will be given an N-ary tree with the root node root as the root of any specific directory. There is no restriction on how the serialization and deserialization algorithm will work. We will just need to ensure that the directory tree can be serialized to a string and that the string can be deserialized back to its original tree structure.

Let’s look at the following examples:
