Some numbers are happy. Some numbers are sad. How can you tell the difference?!

It's actually really easy. Square the number, then square the resulting digits and add them together. Do it again and again... if you get to 1, that number is happy. And if you can't get to 1, the number is stuck in an eternal abyss of sadness and misery.
