thousand, million

Input and Output

Notes on input:
  1. Negative numbers will be preceded by the word negative.
  2. The word “hundred” is not used when “thousand” could be. For example, 1500 is written “one thousand five hundred”, not “fifteen hundred”.
  3. The words “hundred”, “thousand” and “million” are always immediately preceded by a word indicating the numbers one through nine, inclusive.

The answers are expected to be on separate lines with a newline after each.
