Instructions

Write a program that takes a string and displays its last word, followed by a newline ('\n').

  • A word is a section of string delimited by spaces or by the start/end of the string.

  • The output will be followed by a newline ('\n').

  • If the number of arguments is different from 1, or if there are no word, the program displays nothing.

Usage

$ go run . "FOR PONY" | cat -e
PONY$
$ go run . "this        ...       is sparta, then again, maybe    not" | cat -e
not$
$ go run . "  "
$ go run . "a" "b"
$ go run . "  lorem,ipsum  " | cat -e
lorem,ipsum$
$
