Deaf Grandma

This small challenge comes from Chris Pine's "Learn to Program".

Premise

Write a program which can imitate a Grandma who's hard of hearing and follows these rules:

  • If you don't input anything (just hit enter) she responds with WHAT?!
  • If you ask a question with any lower-case letters, she responds with SPEAK UP, KID!
  • If you ask a question in all upper-case letters, she responds with NO, NOT SINCE 1946!
  • The first time you say GOODBYE! she says LEAVING SO SOON?
  • The second time you say GOODBYE! she says LATER, SKATER! and the program exits.

Example

HEY KID!
> hi, grandma
SPEAK UP, KID!
> I SAID HI, GRANDMA
NO, NOT SINCE 1946!
>
WHAT?!
> Goodbye!
SPEAK UP, KID!
> GOODBYE!
LEAVING SO SOON?
> GOODBYE!
LATER, SKATER!

Template

ready_to_quit = false
puts "HEY KID!"

input = gets
until ready_to_quit
  # Your code here
end

puts "LATER, SKATER!"

In your code you'll definitely need to use if and likely an elsif and else. Whenever you're ready to exit the program, set ready_to_quit to true.

Also remember that gets is the "inverse" method of puts -- while puts outputs information to the terminal, gets captures information from the user by presenting a command prompt and allowing them to type input.
