Escreva um programa ou função que leva dois inteiros positivos, uma largura e uma altura, e desenha uma arte ASCII houndstooth padrão de grade com essas dimensões usando essa grade de 25 × 26 texto como a célula de base:

.......#.....#####.......
.......##.....#####......
.......###.....#####.....
.......####.....####.....

.......######.....##.....
.......#######.....#.....
.......########..........

Portanto, se a entrada fosse 2,1a saída, seria:

• O argumento da largura deve vir primeiro. Qualquer formato de entrada razoável (por exemplo w,h, w h, (w, h)) é bom.
• Imprima ou retorne o resultado com uma nova linha à direita opcional.
• Você pode usar dois caracteres ASCII imprimíveis distintos no lugar de .e #.
• Você pode converter a célula base vertical ou horizontalmente, como se tivesse condições de contorno periódicas . Portanto, o canto superior esquerdo da saída não será necessariamente um retângulo 7 × 8 de .'s. ( Nova regra! )

O código mais curto em bytes vence.

Como bônus, gere uma imagem em que cada .um é um pixel de uma cor e cada #um é um pixel de outra cor.

editar 1: Combine as duas instruções que geram a banda e o triângulo (veja abaixo)

editar 2: não viu que podemos usar qualquer símbolo. Salvo 5 bytes editar

edit 3: @ Calvin'sHobbies permitido traduzir a imagem base. Como minha abordagem foi baseada nessa idéia, isso ajudou bastante. -6 bytes

E para o bônus do Cookie :

.w*vw*RQ++Rm012Jmm*K255}k++Rhd5U-d4T=T13+LmKT_mP_dJ

Isso tem apenas 2 bytes mais (51 bytes) e gera o arquivo o.png. Para a entrada 5\n4, gera a seguinte imagem:

Explicação:

O padrão Houndstooth parece realmente bastante irregular. Mas se trouxemos as 7 colunas da esquerda para a direita e as 5 principais linhas para o botão, obtemos um padrão muito melhor:

.#####...................
..#####..................
...#####.................
....#####................

Primeiro, produzo o bloco 13x13 superior esquerdo:

.#####.......
..#####......
...#####.....
....#####....
.....#####...
#.....#####..
##.....#####.
###.....#####
####.....####
#####.....###
######.....##
#######.....#
########.....

Existem 2 desigualdades simples, que descrevem as duas #áreas. A banda pode ser descrita por y + 1 <= x <= y + 5e o triângulo pode ser descrito por x <= y - 5. Eu combinei essas duas condições:

Jmms}k++Rhd5U-d4T=T13
                 =T13   T = 13
 m               T      map each d of [0, 1, ..., 12] to: 
                           the list produced by
  m             T          map each k of [0, 1, ..., 12] to:
       +Rhd5                  the list [d+1, d+2, ..., d+5]
      +                       extended by 
            U-d4              the list [0, 1, ..., d - 5]
    }k                        test if k is in the list
   s                          and convert the boolean result to 1 or 0
J                       assign this 13x13 block to J

Em seguida, +Rm012adiciona 12 zeros no final de cada linha para obter o bloco superior de 25x13.

O bloco inferior de 25x13 agora é realmente simples:

+Lm1T_mP_dJ
      m   J    map each row d of J to:
       P_d        reverse the row and pop the last element
     _         reverse the order the rows
+Lm1T          add T ones at the beginning of each row. 

Tudo o que resta agora é repetir o padrão e imprimi-lo

j*vwmjk*Qd+upperlower   implicit: Q = first input number
          +upperlower   combine the two blocks to a 25x26 block
    m                   map each row d to:
       *Qd                 repeat d Q times
     jk                    and join to a string
 *vw                    read another number from input and repeat
j                       join by newlines and print

A diferença para o código de bônus do Cookie :

• 255 ao invés de 1
• em vez de mjk*Qdusar *RQ, já que não quero uma string
• .w salva esse array 2D em arquivo (o converte em png implicitamente)

(Obviamente, isso ainda é muito jogável. Eu só queria obter uma resposta aqui por enquanto)

Então, isso é composto de partes diferentes.

&&00p10p

Este é apenas o inicializador, pega os valores e os armazena

    >94+2*20p
>00g|      > 
    @  

Esta seção redefine a contagem de linhas, para que possamos imprimir outras fotos (de largura) lado a lado. 94+2*está calculando 26, o número de linhas. Além disso, se a altura for zero, o programa será encerrado.

>10g

Isso fica com a largura da pilha, para que possamos saber quantas imprimir

0020gv-1:<
     >:0`|
         $

Isso adiciona dois valores fictícios à pilha para dizer quando terminamos uma operação, bem como em que linha (n) estamos. Isso adiciona n valores à pilha

>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v>v

Esta é uma seção de controle que irá para a linha (26-n). Esta é a maneira mais fácil de descobrir como fazê-lo.

".......#.....#####......."
".......##.....#####......"
".......###.....#####....."
".......####.....####....."
".......#####.....###....."
".......######.....##....."
".......#######.....#....."
".......########.........."
"####################....."
".####################...."
"..####################..."
"...####################.."
"....####################."
".....####################"
"#.....##############.####"

"#####..#############....."
".#####.#############....."
"..##################....."
"........#####............"
".........#####..........."
"..........#####.........."
"...........#####........."
"............#####........"

Obviamente, isso é lido e exibirá qualquer linha lida na pilha de trás para frente. Isso significa que, quando o abrirmos, ele será impresso corretamente.

v_
,:
>^

Isso será impresso até que a pilha atinja um 0, que deixamos anteriormente.

1-:#^_

Isso retira 1 do número da linha específica a ser impressa e verifica se é zero ou não. Se for diferente de zero, voltaremos ao quarto bloco de código.

          ,
          +
20g1-20p55^

Isso subtrai 1 da linha (n), imprime uma nova linha e volta ao bloco 3

p00-1g00

Uma vez impressas todas as linhas, isso subtrai uma da altura inicial e volta para o bloco 2.

Todo o restante do código é fluxo de controle ou gerenciamento de pilha. Escrever esse mas mais do que eu pensava, mas estou satisfeito com a aparência. É muito mais jogável e provavelmente continuará sendo um projeto por mais um dia.

(Um byte foi adicionado para que o -ncomutador busque entrada de stdin.)

($w,$h)=split;for(1..$h){print((sprintf("%025b",hex)x$w).$/)foreach qw(20f80 307c0 383e0 3c1e0 3e0e0 3f060 3f820 3fc00 1ffffe0 fffff0 7ffff8 3ffffc 1ffffe fffff 107ffef 183ffe7 1c3ffe3 1e3ffe1 1f3ffe0 fbffe0 7fffe0 1f000 f800 7c00 3e00 1f00)}

Isso é bastante simples - basta converter uma matriz de 26 números hexadecimais em binários e imprimi-los o número necessário de vezes.

i,x,y;f(w,h){for(i=26*h*(w*=25);i--;i%w||puts(""))x=i%25,y=i/w%26,putchar(((y>x^y>x+5^x>y+4)&y/13==x/13^y/13)+34);}

9 bytes salvos devido a nova regra que permite a conversão da célula. 3 bytes salvos pelo uso de w*=25. O restante da postagem permanece inalterado.

Rev 0, C, 127 bytes

i,x,y;f(w,h){for(i=650*w*h;i--;i%(25*w)||puts(""))x=(i+20)%25,y=(i/25/w+8)%26,putchar(((y>x^y>x+5^x>y+4)&y/13==x/13^y/13)+34);}

Isso passa pelos caracteres, imprimindo-os um por um. i%(25*w)||puts("")insere uma nova linha no final de cada linha.

Minha maneira de visualizar o design é semelhante à de Jakube, mas trago as 8 linhas superiores para a parte inferior e as 5 colunas da direita para a esquerda para obter a seguinte visualização. No programa, essa etapa é "revertida" por +20e +8nas expressões para x e y.

Além da "inversão de cores", pode parecer muito semelhante, mas há uma diferença importante: as listras diagonais coincidem. (observe que o design original não possui simetria diagonal, pois mede 25x26.)

A expressão ((y>x^y>x+5^x>y+4)^y/13)+34produz o seguinte, onde os vários operadores de comparação produzem as listras, ^y/13produz o "deslocamento da cor" até a metade e +34pega o número resultante 0,1e o eleva para o intervalo ASCII 34,35.

O termo é &y/13==x/13avaliado como false = 0 nos quartos superior direito e inferior esquerdo, produzindo a parte quadrada do padrão, como mostrado anteriormente. Observe que, como o programa reduz a contagem, a origem x = y = 0 está no canto inferior direito. Isso é útil, pois o quadrado de #13 caracteres de largura, enquanto o quadrado de "apenas 12 caracteres de largura.

Explicação amanhã, cama agora. No entanto, direi que faço coisas inteligentes movendo algumas setas de redirecionamento e também uso a propriedade wrap-around bastante. Teste-o neste intérprete online .
