# cleanstr |
||||
## Instructions |
||||
|
||||
Write a program that takes a string, and displays this string with exactly one |
||||
space between words, with no spaces or tabs either at the beginning or the end, |
||||
followed by a \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 \n. |
||||
|
||||
And its output : |
||||
|
||||
```console |
||||
student@ubuntu:~/student/cleanstr$ go build |
||||
student@ubuntu:~/student/cleanstr$ ./cleanstr "you see it's easy to display the same thing" | cat -e |
||||
you see it's easy to display the same thing$ |
||||
student@ubuntu:~/student/cleanstr$ ./cleanstr " only it's harder " |
||||
only it's harder$ |
||||
student@ubuntu:~/student/cleanstr$ ./cleanstr " how funny" "Did you hear Mathilde ?" |
||||
$ |
||||
student@ubuntu:~/student/cleanstr$ ./cleanstr "" | cat -e |
||||
$ |
||||
student@ubuntu:~/student/cleanstr$ |
||||
``` |
