この関数は次のとおりです。

char hash (char* s)

    char r = 0;

    while (*s)
    {
        r += *s|9;
        s++;
    }

    return r%45+77;
}

ゴルフプログラムhashは、文字列または文字の最後に到達するまで入力の関数を計算します-。次に、文字列内のハッシュを検索しk.[<* cKwye(S_-C)7=4&o]sYgmN、対応する番号を決定します。入力文字列の最後に到達した場合は数値が返され、代わりにa -に到達した場合は、数値と入力文字列の残りに適用されたゴルフプログラムの結果が返されます。

使い方

基本的な考え方は、各数字を数字の単語に分割し、各単語を対応する数字にマッピングすることです。ほとんどすべての単語は、単純な正規表現と適切に一致するように設定されていますが、いくつかの異常があります。

• eleventhrough nineteen：単語の途中にel、またはが含まれる場合te（を避けるためten）、on-先頭にaを追加し、これらをon-eleventhrough に変更しますon-nineteen。
• twenty、thirty等：トレーリングを交換yして-d変更これらにtwent-d、thirt-d等

次に、ハイフン、スペース、およびdrsで分割します。これにより、11から99までのすべてが、対応する数字の単語とに"one hundred"分割され[one,hun,ed]ます。次に、これらの各単語を正規表現の配列にマッピングし、最初に一致したもののインデックスを保持します。

0: /un|d/ - This matches the "hun" and "ed" in 100, as well as the "d" we placed on the end of 20, 30, etc.
1: /on|le/ - Matches "one" and the "on" we placed on the beginning of 11 through 19, along with "eleven".
2: /w/ - Matches "two", "twelve", and "twenty".
3: /th/ - Matches "three" and "thirty".
4: /fo/ - Matches "four" and "forty".
5: /f/ - "five" and "fifty" are the only words by now that contain an "f".
6: /x/ - "six" and "sixty" are the only words that contain an "x".
7: /s/ - "seven" and "seventy" are the only words by now that contain an "s".
8: /h/ - "eight" and "eighty" are the only words by now that contain an "h".
9: /i/ - "nine" and "ninety" are the only words by now that contain an "i".
10: /<empty>/ - "ten" is the only word left, but it still has to be matched.

今では、すべての入力が適切な数字の配列になります。私たちがしなければならないのは、それらを結合しjoin``、単項の数に変換するだけ+です。
