Mari bermain golf kode!

Tantangannya adalah menemukan pemenang permainan Tic-Tac-Toe.

Ini telah dilakukan berkali-kali dengan memberikan papan yang memiliki satu pemenang yang jelas tetapi di sini adalah twist:

Sel-sel diberi nomor seperti ini:

1|2|3
-+-+-
4|5|6
-+-+-
7|8|9

Anda mendapatkan larik 9 gerakan seperti itu:

{3, 5, 6, 7, 9, 8, 1, 2, 3}

Ini diuraikan sebagai berikut:

• Pemain 1 menandai sel 3
• Pemain 2 menandai sel 5
• Pemain 1 menandai sel 6
• Pemain 2 menandai sel 7
• Pemain 1 menandai sel 9
• Pemain 1 telah menang

Catatan: Permainan tidak berhenti setelah satu pemain menang, mungkin saja pemain yang kalah berhasil mendapatkan tiga berturut-turut setelah pemain yang menang, tetapi hanya kemenangan pertama yang diperhitungkan.

Tugas Anda sekarang untuk mendapatkan 9 angka sebagai input dan output pemain yang menang dan putaran di mana kemenangan terjadi. Jika tidak ada yang menang, hasilkan sesuatu yang konstan pilihan Anda. Anda dapat menerima input dan memberikan output melalui rata-rata / format standar.

Selamat bersenang-senang!

Beberapa contoh lagi seperti yang diminta:

{2,3,4,5,6,7,1,8,9} => Player 2 wins in round 6
{1,2,4,5,6,7,3,8,9} => Player 2 wins in round 8
{1,2,3,5,4,7,6,8,9} => Player 2 wins in round 8

3:       % Push [1 2 3]
g        % Convert to logical. Gives [true true true]
&+       % Matrix of all pairs of additions. Gives a 3×3 matrix, which represents
         % the board in its initial state, namely all cells contain 2. This value
         % means "cell not used yet". 1 will represent "cell marked by user 1",
         % and 0 will represent "cell marked by user 2"
XI       % Copy into clipboard I
x        % Delete
"        % Implicit input: array with moves. For each move
  I      %   Push current board state
  X@     %   Push iteration index (starting at 1), that is, current round number
  o      %   Modulo 2: gives 1 or 0. This represents the current user
  XK     %   Copy into clipboard K
  @      %   Push current move ((that is, cell index)
  (      %   Write user identifier (1 or 0) into that cell. Cells are indexed
         %   linearly in column-major order. So the board is transposed compared
         %   to that in the challenge, but that is unimportant
  XI     %   Copy updated board into clipboard I
  t!     %   Duplicate and transpose
  y      %   Duplicate from below: push copy of board
  Xd     %   Extract main diagonal as a 3×1 vector
  y      %   Duplicate from below: push copy of transposed board
  PXd    %   Flip vertically and extract main diagonal. This is the anti-diagonal
         %   of the board
  &h     %   Concatenate stack horizontally. This concatenates the board (3×3),
         %   transposed board (3×3), main diagonal (3×1 vector) and anti-diagonal
         %   (3×1) into an 3×8 matrix
  K=     %   Push current user identifier. Test for equality with each entry of the
         %   3×8 matrix
  A      %   For each column, this gives true if all its entries are true. Note 
         %   that the first three columns in the 3×8 matrix are the board columns;
         %   the next three are the board rows; and the last two columns are the
         %   main diagonal and anti-diagonal. The result is a 1×8 vector
  a      %   True if any entry is true, meaning the current user has won
  ?      %   If true
