• Save the tasks in the hard disk automatically whenever the task list changes. Load the data from the hard disk when Duke starts up.
• You may hard-code the file name and location e.g., [project_root]/data/duke.txt

The format of the file is up to you. Example:

T | 1 | read book
D | 0 | return book | June 6th
E | 0 | project meeting | Aug 6th 2-4pm
T | 1 | join sports club

Your code must handle the case where the file doesn't exist at the start. Reason: when someone else takes your Duke and runs it for the first time, the required file might not exist in their computer. Similarly, if you expect the data file to be in as specific folder (e.g., ./data/), you must also handle the 'folder does not exist yet' case.
