ascii-art-justify

Objectives

You must follow the same instructions as in the first subject but the alignment can be changed.

We
        will
                explain!

To change the alignment of the output it must be possible to use a flag --align=<type>, in which type can be :

• center

• left

• right

• justify

• You must adapt your representation to the terminal size. If you reduce the terminal window the graphical representation should be adapted to the terminal size.

• Only text that fits the terminal size will be tested.

• The flag must have exactly the same format as above, any other formats must return the following usage message:

Usage: go run . [STRING] [BANNER] [OPTION]

Example: go run . something standard --align=right

If there are other ascii-art optional projects implemented, the program should accept other correctly formatted [OPTION] and/or [BANNER].
Additionally, the program must still be able to run with a single [STRING] argument.

Instructions

• Your project must be written in Go.
• The code must respect the good practices.
• It is recommended to have test files for unit testing.

Usage

Assume the bars in the display below are the terminal borders:
