Aqui está um simples para esticar seus músculos de compressão. Seu código (um programa completo) deve gerar a representação em inglês de todos os números cardinais de 1 a 100 e, em seguida, todos os números ordinais de 1 a 100. Os números em cada lista devem ser delimitados por vírgulas e espaços e adequadamente hifenizado. Cada lista deve começar com uma única letra maiúscula e concluir com um período. As duas listas devem ser separadas por uma nova linha.

Por uma questão de clareza, você deve produzir este fluxo de bytes exato:

One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, thirty-one, thirty-two, thirty-three, thirty-four, thirty-five, thirty-six, thirty-seven, thirty-eight, thirty-nine, forty, forty-one, forty-two, forty-three, forty-four, forty-five, forty-six, forty-seven, forty-eight, forty-nine, fifty, fifty-one, fifty-two, fifty-three, fifty-four, fifty-five, fifty-six, fifty-seven, fifty-eight, fifty-nine, sixty, sixty-one, sixty-two, sixty-three, sixty-four, sixty-five, sixty-six, sixty-seven, sixty-eight, sixty-nine, seventy, seventy-one, seventy-two, seventy-three, seventy-four, seventy-five, seventy-six, seventy-seven, seventy-eight, seventy-nine, eighty, eighty-one, eighty-two, eighty-three, eighty-four, eighty-five, eighty-six, eighty-seven, eighty-eight, eighty-nine, ninety, ninety-one, ninety-two, ninety-three, ninety-four, ninety-five, ninety-six, ninety-seven, ninety-eight, ninety-nine, one hundred.

Explicações

Consulte Saída formatada para fluxos de caracteres .

• (format t "<control string>" <arguments>)formata a cadeia de controle de acordo com os argumentos (variadic) e imprime na saída padrão (porque t)

• (loop ...) constrói a lista de números inteiros de 1 a 100

• ~@( ... ~) coloca em maiúscula a string retornada pela string de controle interno
• ~{ ... ~} itera sobre o argumento atual e aplica a formatação interna a cada elemento
• Dentro da iteração, tudo o que se segue não~^ é impresso na última iteração: é usado para adicionar o separador de espaço de vírgula entre os elementos.
• ~R gera o argumento atual como um cardeal
• ~:R gera o argumento atual como um ordinal
• ~% gera uma nova linha
• ~:*redefina o argumento atual a ser processado como o anterior, que é usado aqui para reutilizar a lista de números inteiros pela segunda vez.

Explicação

Pode parecer um monte de personagens ilegíveis, mas na verdade é bem simples.

Começamos gerando os cardeais. Essa matriz é compactada usando a btoafunção

['one', ..., 'eighteen', 'nineteen', 'twenty', 'thirty', ...,'ninety']

Para percorrer um "intervalo", usamos o seguinte:

Agora, geramos uma matriz de comprimento 89 usando. O ...é o que descompacta a matriz

Array(89).fill(...)

Então mapeie através dele, i é o índice:

.map((l,i)=>

Agora, para a condição, i < 1ou se for o primeiro item, usaremos uma versão em maiúscula de um / primeiro

i<1?b

Caso contrário ... se for inferior a 20, produzimos onze ... dezenove

i<20?a[i]:

Caso contrário ... usando (i-i%10)/10, obtemos o último dígito do número. Adicionamos 18 a ele para compensar 1..19. Nós adicionamos um -e depois adicionamos o último dígito, ou i% 10

Finalmente, adicionamos 'cem' até o fim, porque não o fazemos.

Repetimos isso para os dois tipos de números e separamos com uma nova linha

Sem as novas linhas. Durante a descompressão, |s são substituídos por '\0'e ~s são substituídos por ' '(peculiaridade da maneira como os caracteres são codificados em ASCII imprimível). Essas seqüências 'primitivas' são pesquisadas pelo índice na bmatriz usando a pfunção e usadas para montar a saída.

A compactação é um esquema simples do tipo LZ, onde os caracteres são codificados como literais ou como um deslocamento negativo no buffer e um comprimento de execução (codificado em dois caracteres) se uma correspondência de comprimento> = 3 for encontrada. A string pode ser compactada ainda mais usando caracteres não imprimíveis, mas eu gosto que meu código seja copiado e colado com segurança :)
