Instructions
Write a program that takes a string
, and displays this string
with exactly:
- one space between words.
- without spaces nor tabs at the beginning nor at the end.
- with the result followed by a newline ("
\n
").
A "word" is defined as a part of a string
delimited either by spaces/tabs, or
by the start/end of the string
.
If the number of arguments is not 1, or if there are no words to display, the
program displays a newline("\n
").
Usage :
$ go run . "you see it's easy to display the same thing" | cat -e
you see it's easy to display the same thing$
$ go run . " only it's harder "
only it's harder$
$ go run . " how funny" "Did you hear Mathilde ?"
$ go run . ""
$
