## rostring
### Instructions
Write a program that takes a `string` and displays this `string` after rotating it
one word to the left.
Thus, the first word becomes the last, and others stay in the same order.
6 years ago
A word is a sequence of **alphanumerical** characters.
Words will be separated by only one space in the output.
If the number of arguments is different from 1, the program displays a newline.
