Objective

Write a program that normalizes one string argument by printing its words separated by exactly three spaces.

Steps

• The program expects exactly one argument.
• A word is a run of characters that is not a space or a tab.
• Skip leading and trailing spaces or tabs from the input.
• Print each word in its original order.
• Place exactly three spaces between consecutive words.
• If the argument count is wrong, print wrong number of arguments followed by a newline. If the input contains no words, print only a newline.
• Use only write.
