clean_words

Words and tokens16

Objective

Write a program that takes a single string argument and prints it with all whitespace runs collapsed to a single space and no spaces at the start or end.

Steps

A word is any sequence of characters that is not a space or a tab.
Every run of one or more spaces or tabs between two words must be replaced by exactly one space.
The output must not start or end with a space.
If the program receives anything other than exactly one argument, print wrong number of arguments followed by a newline.
Use only write.
