Whoozit.

-The program should ask the user to "Enter an alien word:", read the input as a string, and check whether or not it is a valid word (Blurb). If it is valid, it prints "The word is fine.", otherwise it prints "The word is a mess!".

-The program should loop and ask the user for new input until they enter a valid blurb.

For Scheme, it is suggested that you review the "input_and_output.rkt" sample program from the first module on functional programming. This program shows how to perform a "loop" that reads in data and processes it. You may find the following forms useful:
a. (read) to read a string
b. (string->list) to convert the string into a list of characters,
c. (display "Hello") to write Hello to the screen.
d. (begin) to help with displaying an output while not breaking out of the running procedure.
