◆LETTER COUNT

The letter count of a number is defined as the number of letters in English
spelling of that number. Letters in linking words such as 'and' are not
counted. Find the largest number having these properties:

-Its letter count is same as sum of the letter counts of each of its digits.
-No digit is used more than twice.
-Does not start with zero.

Exampe: 5010
"FIVE THOUSAND TEN" has 15 letters.
"FIVE ZERO ONE ZERO" has 15 letters.

一個數字的字母量定義為其英文拼法的字母數量。用於單字連接詞之字母如'and'不算。
試尋滿足以下三個條件之最大數字：

-其字母量等同於每個位數字母量之和。
-每位數字出現不超過兩次。
-不得以零開頭。

範例： 5010
"FIVE THOUSAND TEN" 有十五個字母。
"FIVE ZERO ONE ZERO" 有十五個字母。
