Objectives

Ascii-art is a program which consists in receiving a string as an argument and outputting the string in a graphic representation using ASCII. Time to write big.

What we mean by a graphic representation using ASCII, is to write the string received using ASCII characters, as you can see in the example below:

@@@@@@BB@@@@``^^``^^``@@BB$$@@BB$$
@@%%$$$$^^^^WW&&8888&&^^""BBBB@@@@
@@@@@@""WW8888&&WW888888WW``@@@@$$

• This project should handle an input with numbers, letters, spaces, special characters and \n.
• Take a look at the ASCII manual.

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.

• Some banner files with a specific graphical template representation using ASCII will be given. The files are formatted in a way that is not necessary to change them.

  • shadow
  • standard
  • thinkertoy

Banner Format

• Each character has a height of 8 lines.
• Characters are separated by a new line \n.
• Here is an example of ' ', '!' and '"'(one dot represents one space) :

......
