설명

코드는 복잡한 번호를 사용 0, 1, j각각 자고, 빈, 웨이크 : 세 가지 상태를 나타냅니다.

Q         % Implicitly input n. Add 1
tE        % Duplicate and multiply by 2
:         % Range [1 2 ... 2*n]
=         % Test for equalty. Gives [0 ... 0 1 0... 0], with 1 at position n
&*        % Matrix of all pairwise products. Gives square matrix of size 2*n
          % filled with 0, except a 1 at position (n,n). This is the grid
          % where the walk will take place, initiallized with an awake cell
          % (value 1). The grid is 1 column and row too large (which saves a
          % byte)
G:"       % Do n times
  tt      %   Duplicate current grid state twice
  0=      %   Compare each entry with 0. Gives true for empty cells, false
          %   for the rest
  w       %   Swap: moves copy of current grid state to top
  1Y6     %   Push 3×3 matrix with Von Neumann's neighbourhood
  Z+      %   2D convolution, maintaining size
  Xj      %   Real part
  1=      %   Compare each entry with 1. This gives true for cells that
          %   have exactly 1 awake neighbour
  *       %   Multiply, element-wise. This corresponds to logical "and":
          %   cells that are currently empty and have exactly one awake
          %   neighbour. These become 1, that is, awake
  w       %   Swap: moves copy of current grid state to top
  |g      %   Absolute value, convert to logical: gives true for awake or
          %   sleeping cells, false for empty cells
  J*+     %   Mulltiply by j and add, element-wise. This sets awake and
          %   sleeping cells to sleeping. The grid is now in its new state
]         % End
Q         % Add 1, element-wise. Transforms empty, awake, sleeping
          % respectively from 0, 1, j into 1, 2, 1+j
|U        % Abolute value and square, element-wose. Empty, awake, sleeping
          % respectively give 1, 4, 2
31+c      % Add 31 element-wise and convert to char. Empty, awake, sleeping
          % respectively give characters ' ' (codepoint 32), '#' (codepoint
          % 35) and '!' (codepoint 33). Implicitly display
