Ringkasan

Seorang guru disuruh menyiapkan soal kata untuk para siswa. Dia diberi daftar persamaan dan diminta untuk menuliskannya sebagai kata yang sesuai. Namun, dia sangat malas, jadi dia tidak menaruh banyak kreativitas di dalamnya. Sebaliknya, ia hanya menulisnya secara harfiah. Misalnya, ketika dia membaca 1+1, dia menulis one plus one, 47 * 2akan berubah menjadi forty seven times two, dan 56.2 / 7.4akan menjadi fifty six point two divided by seven point four.

Tulis beberapa kode untuk membantu guru malas ini.

Detail

• Angka mungkin termasuk titik desimal dan tanda negatif.
• Angka harus ditulis dalam skala pendek. (yaitu, 1,000,000,000adalah one billion)
• Angka bisa mencapai 999.999.999.999.999.999 ( nine hundred ninety nine quadrillion...nine hundred ninety nine).
• Grup nol harus ditinggalkan. misalnya 1,000,000adalah one milliontidak one million zero thousand zero hundred.
• Dapat ada banyak digit yang melewati titik desimal.
• Digit setelah titik desimal harus dicantumkan digit demi digit. misalnya 12.34adalah twelve point three fourtidak twelve point thirty four.
• Dua angka selalu dipisahkan oleh operator.
• Operator yang valid adalah plus ( +), minus ( -), times ( *), dan dibagi dengan ( /).
• Tidak ada tanda kurung.
• Angka-angka seperti 1234opsional dapat termasuk anddalam output mereka, seperti dalam one thousand two hundred *and* thirty four.
• Koma dan spasi putih pada input mungkin diabaikan.

Keluaran:one plus negative one

Input: 1,000,000,000 + 0.2
Keluaran:one billion plus zero point two

Input: 123,000,456,789,012,345.6789
Keluaran:one hundred twenty three quadrillion four hundred fifty six billion seven hundred eighty nine million twelve thousand three hundred forty five point six seven eight nine

Input: -4.3 * 7
Keluaran:negative four point three times seven

Input: -1-1--1
Keluaran:negative one minus one minus negative one

Pasti ruang untuk perbaikan di sini. Saya mengatakan itu, tetapi saya terus memperhatikan kasus tepi yang belum saya tangani :(. Mengasumsikan bahwa input memiliki operator yang dipisahkan oleh spasi dan negatif dari angka tidak dipisahkan.

Penjelasan:

my&n=(*+1632+|0).uniname.lc.words[2..*]  # Define a helper function
           # This gets the unicode name, e.g ARABIC-INDIC DIGIT ZERO
           #                              or AEGEAN NUMBER ONE HUNDRED
           # And returns the 3rd word onwards in lowercase e.g. 'zero' or 'one hundred'
{S:g/\-(\d)/negative $0/}  # Turn dashes before numbers to negative
{S:g/[\s|^]0/ zero/}       # Handle zeros
{S:g/\.(\d)+/ point {$0>>.&n}/}  # Replace decimals
{~S:g/\d+/        # Replace series of numbers with
    n($//100+64184)x($/>100)  # The hundreds if the num is bigger than 100
    $/%100>19&&               # If the number is bigger than 19
      (
      n($//10%10+64175),         # The tens number
      n($!=$/%10)x?$!            # And the singles number (if it's not zero)
      )
    ||                        # Else
      n($/%100+7679)             # The name of the number below 20

Saya pasti tergila-gila untuk mengusulkan solusi Frankenstein seperti itu, tetapi di satu sisi, sangat menggoda untuk menggunakan fungsi bawaan Swift untuk tugas ini, dan di sisi lain, memproses string dengan Regexes di Swift tampaknya menjadi bencana golf.

Oleh karena itu, saya memutuskan untuk melakukan pemrosesan string dasar di Ruby, tetapi untuk menjabarkan angka, saya menyimpannya dalam file sumber Swift, menjalankan Swift dalam perintah shell, dan mengumpulkan hasilnya.

Saya ternyata formatter angka "spellOut" Swift melakukan hampir semua yang kita butuhkan, kecuali memasukkan tanda hubung yang tidak perlu untuk angka dua digit, seperti pada twenty-two . Bahkan, bahkan output floating point dalam format integer part point digit digit...yang baik, tetapi inilah peringatan - tidak ada ketepatan tak terbatas, dan dengan angka yang cukup besar atau banyak angka desimal, hasilnya salah. Karena itu, saya harus memisahkan bagian bilangan bulat dan pecahan dan untuk memberi makan fraksi digit demi digit.

# using enumerate (E) even though i is not required b/c it's shorter than range(len(x))
# using re.split (S) instead of string.split since it's shorter
