Instructions

Write a program that takes a string as a parameter, and prints its words in reverse, followed by a newline.

• A word is a sequence of alphanumerical characters.

• If the number of arguments is different from 1, the program will display nothing.

• In the parameters that are going to be tested, there will not be any extra spaces. (meaning that there will not be additional spaces at the beginning or at the end of the string and that words will always be separated by exactly one space).
