Replace with antonyms
Create a program that replaces all the words from the command line with their antonyms. If the word is missing in the dictionary, do not modify it and print as-is.
Use a hard-coded hash to keep the dictionary of antonyms. For your convenience, here is a prepared list of about 200 pairs that you can directly copy and paste into your program: dictionary.raku. All the pairs are kept in both directions, e.g.:
my %dictionary = 'above' => 'below', 'absent' => 'present', # . . . 'below' => 'above', # . . . 'present' => 'absent', # . . . ;
Make the program as simple as possible and print the words line by line.
Run the program and pass a few words to it. Make sure that at least some of the words can be found in the dictionary.
