final_token

Your mission

Write a program that receives exactly one string argument and prints its last word followed by a newline.

./final_token "llm says works on my branch" | cat -e

Expected result

Your checklist

For your own tracking. Tests grade your code.

A word is a sequence of non-whitespace characters. Spaces and tabs act as delimiters.
Skip any trailing spaces or tabs before locating the last word.
If the program does not receive exactly one argument (argc must be 2), print wrong number of arguments followed by a newline. If no word is found, print only a newline.
