Complete the program below to allow it to extract ALL of the words$/$tokens

that are supplied as command line parameters to your program.

You will put the string that you are wanting to pass to your program

inside double quotes so it will be passed, intact, as a single

command line parameter $($see sample output below$).$

One simplifying assumption that we will make is that all of our data

will have exactly one space between words and no spaces at the beginning

or end of the string. $($again$,$ see sample output below$)$

I've provided you with a start for your program. You do not need to

write any additional classes or methods.

No spilt or for loop, Has to be a WHILE LOOP
