How to Run:

1. Download the Repository as ZIP from GitHub.
2. Extract the ZIP file. (alternatively downloading package/ and runApp.sh works too)
3. Open a Terminal / Command Prompt in the extracted directory's location (OR navigate into the extracted directory using cd command).
4. Run command: ./runApp.sh src/resources/input.txt

To try with a separate file,

• Either edit src/resources/input.txt OR
• Create a new file and run the command with path of the new file. (i.e. ./runApp.sh file_path)

Troubleshooting:

If Permission denied on running the shell script -> Run command: chmod 555 runApp.sh and try again.

Notable Features:

• Opens this README page in default browser in case of incorrect way of executing the shell script.
  (e.g., no input file path passed as argument, or file not found)
• Thread-safe way of handling each command using Read Write Lock & Atomic Integer.
