Challenge 11

Problem

Create a program that, given an integer 0 through 999,999, does the "4 is magic" transformation. If you don't know what that is, this is it:

* Take the number written out in English and count the number of letters (i.e. 21 is "twenty-one" is 9 letters, 102 is "one hundred two" is 13 letters, 9999 is "nine thousand nine hundred ninety-nine" is 33 letters).
* If the result is 4, output "4 is magic." and exit.
* Else, output "(original number) is (result)." and repeat step 1 with the result.Example:
--- Code: ---31 is 9.
9 is 4.
4 is magic.
--- End code ---

-70% bonus if you actually display the number-words instead of the numbers.

Yay, got it to 562-70%=168.6 characters in Ruby.

EDIT: 559-70%=167.7 now. Also I have a few questions:
- Do I have to print "4 is 4" with an input of 4? (No would save a few bytes)
- "Ninety-nine" or "ninety nine"? Does it matter? (No would save one byte)
- Capital letter at the beginning? (No would save a few bytes)

1. No, input of 4 means instant input of "4 is magic".
2. It shouldn't matter, but that's how I write numbers, usually. Do it if you want.
3. Whatever you want, but it's common courtesy to.

Juju:
Thanks, that answers my questions, I'll send you my 558-byte solution now.

It works, and well at that! :thumbsup:
