expandstr
Instructions
Write a program that takes a string and displays it with exactly three spaces between each word, with no spaces or tabs either at the beginning or the end, followed by a newline.
A word is a section of string delimited either by spaces/tabs, or by the start/end of the string.
If the number of parameters is not 1, or if there are no words, simply display a newline.
