Tugas Anda, untuk golf ini, adalah menulis program yang akan memindahkan permainan reversi (othello) dan menampilkan hasilnya kepada pengguna.

Memasukkan

Sederetan angka diambil dari kisaran [0-7]. Setiap pasangan angka pertama mewakili koordinat X, kemudian koordinat Y. Karakter apa pun yang tidak berada dalam rentang itu harus diabaikan.

Keluaran

Representasi visual dari hasil permainan, termasuk siapa yang memimpin ketika input berakhir. Ini mungkin keluaran grafis atau keystroke, tetapi harus berupa kotak visual permainan, dengan karakter / simbol grafis yang berbeda untuk hitam, putih, dan kosong.

Selain itu, kode Anda harus menampilkan pesan kesalahan dan berhenti ketika langkah ilegal dimasukkan (kotak yang sama lebih dari sekali, atau kotak yang tidak akan membalik ubin apa pun).

Lompatan harus ditangani dengan anggun. Lompatan terjadi ketika satu warna tidak memiliki gerakan hukum, giliran mereka dilewati dan pemain lain dapat bermain.

Hitam selalu menjadi yang utama.

Dalam versi ini, tidak ada pesan kesalahan yang terperinci dan hasilnya jauh lebih mendasar. Perubahan besar diganti Either String adengan Maybe adan karena mereka berdua monad, ini dicapai dengan hanya bertukar Right adengan Just adan Left Stringdengan Nothing.

Tes

Dengan tangkapan layar untuk mencegah luka bakar mata.

$ printf "232425140504032627" | ./rve

$ printf "2324" | ./rve

$ printf "1" | ./rve
invalid coordinates string

$ printf "24" | ./rve
wrong move (2,4).

Apakah mungkin untuk mendapatkan impossible move (x,y)ketika Anda menggunakan innardics (fungsi dari jeroan program dan bahwa Anda tidak boleh menggunakan) dan x/y is out of bounds.
