Ini memberikan output ini untuk input sampel:
(~(((5)X(4))O(3)))a(~(1))
((~(((5)X(4))O(3)))a(~(1)))X(((2)x(1))x(3))
Untuk memeras ukurannya:
- Itu tidak melakukan pengecekan kesalahan, penanganan kesalahan atau validasi input, dengan asumsi bahwa input selalu valid.
- Terbatas hingga 99 baris input.
- File inputnya harus dipanggil adil
r
, tanpa ekstensi file apa pun dalam namanya.
- Itu tidak berusaha untuk mendeteksi apakah tanda kurung diperlukan atau tidak. Ini mengasumsikan bahwa mereka selalu diperlukan, dan karena asumsi ini salah, ada kurung lebih banyak dari yang dibutuhkan, tetapi karena ini tidak membuatnya gagal spec, itu tidak masalah.
- Urutan parameter untuk setiap operator biner secara umum tidak dapat diprediksi, karena tergantung pada kecepatan nilai-nilai tersebut diperbanyak dan dari urutan pemindaian sel. Tetapi karena semua operator biner bersifat komutatif, ini seharusnya tidak menjadi masalah.
Saya yakin itu mungkin untuk mengurangi lebih banyak, tetapi hanya sedikit.
Penerjemah diimplementasikan dalam bentuk semacam automata seluler. Ini memindai seluruh nilai pengaturan bidang, mengulanginya sebanyak yang diperlukan hingga tidak ada perubahan yang terdeteksi.
