Tantangan ini adalah untuk mencetak angka Cribbage hand. Jika Anda tidak bermain Cribbage, Anda harus belajar. Kami bermain dengan setumpuk poker standar, dan satu tangan terdiri dari empat kartu plus "kartu naik". Ada dua jenis tangan: normal, dan 'boks tangan'.

Kartu datang dalam format di vsmana vsalah satu dari: A23456789TJQK(T untuk sepuluh) dan ssalah satunya SCDH. Tangan akan diberikan dalam bentuk (misalnya)

AS 2D 3H JS | 4S

dimana 4Skartu up. Boks tangan akan memiliki format

JD 3C 4H 5H | 5S !

Kartu wajah memiliki nilai 10, dan kartu as memiliki nilai 1. Penilaian dilakukan sebagai berikut.

• Fifteens: untuk setiap subset dari lima kartu yang jumlahnya 15, tambahkan dua poin.
• Pasangan: untuk setiap pasangan kartu dengan peringkat yang sama (bukan nilai), tambahkan dua poin.
• Run: untuk setiap run maksimal kartu berturut-turut dengan panjang lebih dari 2, tambahkan panjang run dalam poin.
• Siram: jika kelima kartu memiliki jenis yang sama, tambahkan lima poin. Kalau tidak, jika semua kecuali kartu naik adalah jenis yang sama, tambahkan empat poin. Jika ini adalah boks tangan, varian empat poin tidak dihitung.
• Nobs: jika ada jack di tangan dengan kartu yang sama di atas, tambahkan satu poin.

Catatan:

• Triples dan merangkak dari jenis tidak istimewa - ada tiga pasang dalam tiga, sehingga tiga bernilai 6 poin.

• Berjalan bisa tumpang tindih. Misalnya, AS AH 2D 3C | 2C(lari ganda ganda) memiliki empat kali panjang 3 dan dua pasang, jadi bernilai 3 + 3 + 3 + 3 + 2 + 2 = 16 poin.

• Hanya lari maksimal yang dihitung, jadi KS QD JD TC | 9Sbernilai 5 poin, karena ini adalah lari 5. Sub-lari tidak dihitung.

Aturan Rumah:

Tidak mungkin untuk mencetak 19 poin di tangan. Alih-alih nol, laporkan skor 19.

Contoh:

5S 5H 5D JS | KS
21

AS 2D 3H JS | 4S !
9

JD 3C 4H 5H | 5S
12

9S 8S 7S 6S | 5H !
9

9S 8S 7S 6S | 5H
13

8D 7D 6D 5D | 4D !
14

8D 7D 6D 5D | 4D

Karena saya tidak pernah bermain cribbage, saya tidak tahu trik mencetak gol yang bagus. Karena itu saya pikir satu-satunya cara untuk bersaing (setidaknya sedikit) adalah menggunakan bahasa golf. Kode GolfScript cukup sederhana, kasus uji dapat ditemukan di sini .

Kode dengan cara yang lebih mudah dibaca ( diformat ulang dan sedikit tidak diolah ):
