- All solutions must be solved using Java FP
- One application for all the requirements
- Non-interactive
- The application will not request any input from the user. Just read the CSV
- Do not alter the given CSV files
- Do not create new files, just print the result in the screen using
System.out
- "Print the month" means print the english name of the month (i.e.
August
instead of08
) - "...from all branches" means data from all CSV files will be combined
- "Print the total sales of each branches" is expected to output 3 numbers
- printing string results (month/item name) is cAsE-iNseNsiTiVe
