## expandstr
### Instructions
Write a program that takes a `string` and displays it with exactly three spaces between each word, with no spaces or tabs at either the beginning nor the end.
5 years ago
The `string` will be followed by a newline (`'\n'`).
A word is a sequence of alphanumerical characters.
If the number of parameters is not 1, or if there are no word, the program displays nothing.
