Below, you can find another hint for the Challenge.
You should only get here after reading, digesting, and applying the .
The part of the program where the string literal is reproduced needs to be adapted, because it still outputs one string literal on a single line. This concerns the statements:
Instead of putting the entire string S on a single line, it needs to process S more carefully. For instance, by looping over it character by character, and whenever a newline marker was encountered, a line break should be introduced, consisting of a closing quote, a plus symbol, a newline, two spaces indentation, and an opening quote.
Can you develop this into a first solution?
Try your program in the machine, and see if you can extend it to a complete solution.
It is your turn ...
