Versi sederhana dari kalkulator angka bahasa Inggris

Tugas

Tulis program yang menggunakan string sebagai input dan output hasil dari ekspresi.

Aturan

String input akan dikata dan bukan bilangan.

Tidak akan ada tanda kurung.

Urutan perhitungan akan dibagi, dikalikan, kurangi kemudian tambahkan.

Untuk operasi yang sama, perhitungan harus dilakukan dari kiri ke kanan.

Semua angka input akan berupa bilangan bulat dari -999 hingga 999 (keduanya termasuk)

Output akan menjadi bilangan bulat dari rentang apa pun.

Pembagian akan selalu dapat dibagi dengan sempurna dan nol tidak akan pernah menjadi penyebut.

Pembatasan case untuk input adalah opsional. Anda tidak perlu memeriksa validitas input.

Format Angka

0 to 20 -> zero,one,two...nineteen,twenty
21 to 99 -> twenty one,twenty two.....ninety eight,ninety nine
100 to 999 -> one hundred, one hundred one, one hundred two...one hundred ten....two hundred fifty....nine hundred ninety eight,nine hundred ninety nine

Untuk angka negatif: Tambahkan minuske ekivalen positifnya

Format Operasi

Addition: one plus two
Subtraction: one minus two
Multiplication: one time two #Note that for one on the left of multiplication, it is one time and not times.
                two times one hundred
Division: forty divided by two

Contoh:

o/p <- input

20     four times five
35     twenty plus fifteen
70     fifty plus five times four
-90    minus one time ninety
25     twenty one minus minus four
45     ninety divided by two
700    one time seven hundred 
555    one hundred eleven times two plus three hundred thirty three
99     one hundred plus minus one
45     forty five plus two hundred times zero
 4     four
-3     three minus three minus three

Contoh langkah demi langkah:

• Memasukkan: two hundred twenty two divided by two times minus fifty seven plus three hundred eighteen minus minus ten
• Langkah 1: Hapus "oleh": two hundred twenty two divided two times minus fifty seven plus three hundred eighteen minus minus ten
• Langkah 2: Ubah "nol" menjadi "dua belas" dengan angka yang benar: 2 hundred twenty 2 divided 2 times minus fifty 7 plus 3 hundred 8een minus minus 10
• Langkah 3: Hapus semua "t": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8een minus minus 10
• Langkah 4: Ganti semua "een" dengan "+10": 2 hundred weny 2 divided 2 imes minus fify 7 plus 3 hundred 8+10 minus minus 10
• Langkah 5: Ganti semua "seratus" dengan "* 100": 2 *100 weny 2 divided 2 imes minus fify 7 plus 3 *100 8+10 minus minus 10
• Langkah 6: Ganti semua ["wen", "hir", "untuk", "fif"] dengan digit yang benar: 2 *100 2y 2 divided 2 imes minus 5y 7 plus 3 *100 8+10 minus minus 10
• Langkah 7: Ganti semua "y" dengan "* 10": 2 *100 2 *10 2 divided 2 imes minus 5 *10 7 plus 3 *100 8+10 minus minus 10
• Langkah 8: Dibagi dengan ["plus", "minus", "ime", "imes", "dibagi"]: ["2 *100 2 *10 2 "," 2 "," "," 5 *10 7 "," 3 *100 8+10 "," "," 10"]
• Langkah 9: Bagi masing-masing pada spasi: [["2","","*100","2","*10","2",""],["","","2",""],["",""],["","5","*10","7",""],["","3","","*100","8+10",""],["",""],["","10"]]
• Langkah 10: Hapus item kosong: [["2","*100","2","*10","2"],["2"],[],["5","*10","7"],["3","*100","8+10"],[],["10"]]
• Langkah 11: Bagi menjadi beberapa ukuran 2 dan bergabung: [["2*100","2*10","2"],["2"],"",["5*10","7"],["3*100","8+10"],"",["10"]]
• Langkah 12: evalSetiap Python :[[200,20,2],[2],"",[50,7],[300,18],"",[10]]
• Langkah 13: Jumlahkan masing-masing: [222,2,"",57,318,"",10]
• Langkah 14: Dorong kembali string dari register, dan hapus semuanya kecuali huruf: dividedimesminusplusminusminus
• Langkah 15: Ganti "plus", "minus", "imes", "ime", "dibagi" dengan karakter operator, dan tambahkan mereka dengan spasi: [" /"," *"," -"," +"," -"," -"]
• Langkah 16: Jalin dan gabungkan keduanya: 222 /2 * -57 +318 - -10
• Output: Python evalstring, dan output secara implisit:-5999.0
