You will convert numbers from words to numerals.

The numbers will be non-negative integers less than one billion. Their word representations will be <number>s according to the following BNF grammar:

<ones> ::= "one" | "two" | "three" | "four" | "five" | "six" | "seven" | "eight" | "nine"
<tens-place> ::= "twenty" | "thirty" | "forty" | "fifty" | "sixty" | "seventy" | "eighty" | "ninety"
<tens> ::= <ones> | <tens-place> | <tens-place> "-" <ones> | "ten" | "eleven" | "twelve" | "thirteen" | "fourteen" | "fifteen" | "sixteen" | "seventeen" | "eighteen" | "nineteen"
<hundreds> ::= <tens> | <ones> " " "hundred" | <ones> " " "hundred" " " <tens>
<thousands> ::= <hundreds> | <hundreds> " " "thousand" | <hundreds> " " "thousand" " " <hundreds>
<millions> ::= <thousands> | <hundreds> " " "million" | <hundreds> " " "million" " " <thousands>
<number> ::= <millions> | "zero"
