Saya tidak mendapatkan bagian dengan data acak. Apakah saya tidak memerlukan akun yang harus saya bayar untuk mendapatkan data?
Sangat naif. Berikut kode yang dihasilkan untuk "1Aa" (49, 65, 97) dengan sedikit dokumentasi:
// field 0 and 1 are loop counters.
// The fields 2, 3 and 4 are for "1", "A" and "a"
++++++++++[ // do 10 times
>
++++++++++[ // do 10 times
> // "1" (49) is below 50 so we don't need to do anything here
>+ // When the loops are done, this part will have increased the value of field 3 by 100 (10 * 10 * 1)
>+ // same as above
<<<- // decrease inner loop counter
]
>+++++ // this will add 50 (10 * 5) to field 2, for a total of 50
>---- // subtract 40 from field 3, total of 60
> // Nothing done, value stays at 100
<<<<- // decrease outer loop counter
]
>>-. // subtract 1 from field 2, total now: 49, the value for "1"
>+++++. // add 5 to field 3, makes a total of 65, the value for "A"
>---. // subtract 3 from field 4, total of 97, the value for "a"
Kode Java agak jelek tapi berfungsi. Instruksi yang dihasilkan per rasio byte input mungkin lebih baik semakin tinggi nilai byte rata-rata.
Jika Anda ingin menjalankannya, Anda harus meletakkan Lenna.png di direktori yang sama dengan file .class. Ini mencetak skor untuk menghibur dan menulis kode BF yang dihasilkan ke dalam file yang disebut "output.txt".

Saya akan membuat beberapa perbaikan kecil tapi mungkin tidak banyak. Selesai
