Convert integer to English
  • Given a non-negative integer up to $999\\,999\\,999$, write it in English.
  • The input number can be in any form other than English (though you'll typically want to use the native integer type of your language).
  • <s>When there are several variants of writing the number in English, you can choose whichever suits you more. For example, the input $120$ may give the output `one hundred twenty` or `one hundred and twenty`.</s>
  • The numbers must be formatted as follows:
  • * Two-digit numbers must be written with dashes where applicable e.g. `twenty-five`, not `twenty five`.
  • * powers of ten start with “one”, e.g. `one hundred`, not just `hundred`.
  • * The tens/ones part, if not zero, must be separated from the hundreds part with `and`, e.g. `two hundred and five`, not `two hundred five`.
  • * The above rules are applied also to the factors of thousand and million.
  • * moreover the global tens/ones part has bto be separated by `and` whenever *anything* larger is present, even if the hundreds part is missing.
  • * Adjacent words must be separated by a single space, or a single dash without space where applicable.
  • * Leading and/or trailing spaces are not allowed. However, if the result is printed, a single trailing newline (not preceded by any spaces) is allowed.
