From 077aa55cfb68bbb6aae0440256cd8d8778451e7f Mon Sep 17 00:00:00 2001
From: Mahmoud Emad <mahmmoud.hassanein@gmail.com>
Date: Sun, 23 Jun 2024 17:38:20 +0300
Subject: [PATCH] chore: Replaced the `rootFS` function with the GC:

- Removed the `rootFS` function/file.
- Updated the solutions with the newly implemented `calculateRootFileSystem`.
- Removed the un-needed debug logs.
- Docstring the newly implemented function.
