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.

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.
