Write a program that reads a text in an endless loop, every single word
flipped over and then put back together as text. If the input is empty, the program should
abort, stop.
To do this, write a reverseWords::String -> String function that does the reversing
is working.
for example:
reverseWords "Hello World, 123" -> "olleH ,dlroW 321"
my code
reverseWords :: String -> String
reverseWords = unwords . reverse . words
doesnt work
>Solution :
The function reverse reverses the entire list, so you are getting the words in the reverse order. What you want instead, is to reverse each element separately, which can be fixed with map:
reverseWords = unwords . map reverse . words
