Isi langkah-langkahnya (secara acak)!

8

Ini adalah Hole-9 dari The Autumn Tournament dari APL CodeGolf . Saya adalah penulis asli masalah di sana, dan dengan demikian diizinkan memposting ulang di sini.

Diberikan array Boolean sederhana (persegi panjang, tidak bergerigi) (dari satu dimensi atau lebih) mengembalikan daftar array yang berbentuk demikian di mana array pertama identik dengan input dan yang terakhir semuanya benar. Semua langkah perantara harus memiliki satu kebenaran lebih dari tetangganya di sebelah kiri (tetapi jika tidak identik). Untuk setiap langkah, bit yang diubah harus dipilih secara semu (dan Anda dapat mengambil seed jika perlu).

Contohnya

[0] memberi [[0],[1]]

[[0]] memberi [[[0]],[[1]]]

[[[1,1,1],[1,1,1],[1,1,1]],[[1,1,1],[1,1,1],[1,1,1]],[[1,1,1],[1,1,1],[1,1,1]]] memberi [[[[1,1,1],[1,1,1],[1,1,1]],[[1,1,1],[1,1,1],[1,1,1]],[[1,1,1],[1,1,1],[1,1,1]]]]

Hasil contoh-contoh berikut tentu saja dapat bervariasi karena keacakan; ini hanya contoh dari output yang valid:

[0,1,0,0] memberi [[0,1,0,0],[1,1,0,0],[1,1,0,1],[1,1,1,1]]

[[0,1,0],[0,0,1]] memberi [[[0,1,0],[0,0,1]],[[1,1,0],[0,0,1]],[[1,1,0],[0,1,1]],[[1,1,1],[0,1,1]],[[1,1,1],[1,1,1]]]

Tantangan ini benar-benar membuat saya mulai mempertanyakan keputusan yang dibuat pengembang R / S ...
Giuseppe
Pengembang @Giuseppe R / S?

R (dan S-plus) adalah implementasi S, jadi banyak fungsi dasar R mengoperasikan cara yang ditentukan S mereka, atau dipertahankan untuk memungkinkan kompatibilitas dengan S (atau lebih buruk, S-plus). Saya tidak yakin siapa yang harus disalahkan atas beberapa perilaku tak terduga yang saya temui ketika mencoba menyelesaikan beberapa tantangan ini!

F             Flatten A.

              unique. Yield the array of all unique results.
      ¦         Sparse application:

  0               Replace the element at that index with 0.
         ¬    Once again negate all Booleans.

FoldList[ReplacePart[#,#2->1]&,#,RandomSample@Position[#,0]]&

Cobalah online!

Penjelasan

Position[#,0]

Temukan semua posisi 0s dalam array bersarang.

RandomSample@...

Kocok daftar posisi.

FoldList[...&,#,...]

Lipat fungsi di sebelah kiri di atas daftar posisi yang dikocok, menggunakan input sebagai nilai awal, dan kumpulkan semua langkah operasi lipatan di hasilnya.

ReplacePart[#,#2->1]

Tetapkan nilai pada posisi yang diberikan ke 1.

R , 93 82 74 byte

function(a)Reduce(function(x,y){x[y]=T;x},sample(as.list(which(!a))),a,,T)

Cobalah online!

Mengambil R logical arraydan mengembalikan listdari logical arrays.

Jahat sample(as.list(which(!a)))adalah untuk mencegah kasus tepi di sample. Ketika aberisi tepat satu FALSEnilai pada indeks i, samplemengembalikan permutasi acak 1:idaripada sampel ukuran acak 1yang hanya berisi nilai i, jadi saya digunakan as.listuntuk mencegah which(!a)dari menjadi numeric.

Dokumentasi R untuk samplesedikit meminta maaf tentang perilaku ini:

Jika xmemiliki panjang 1, adalah numerik (dalam arti is.numeric) dan x >= 1, pengambilan sampel melalui sampel dilakukan mulai 1: x. Perhatikan bahwa fitur kenyamanan ini dapat menyebabkan perilaku yang tidak diinginkan ketika x memiliki panjang panggilan yang bervariasi seperti sample(x).
