四是魔数

26

在发布此挑战之前，我没有检查沙盒 -似乎是CᴏɴᴏʀO'Bʀɪᴇɴ提出的挑战。

给定一个整数输入，编写一个打印“四是一个魔术数字”之谜的程序

  • 四是魔数
  • 五是四，四是魔数
  • 六是三，三是五，五是四，四是魔数
  • 十一是六，六是三，三是五，五是四，四是魔数
  • 五百是十一，十一是六，六是三，三是五，五是四，四是魔数

如果您已经知道了谜语，或者太懒了而无法解决它，就急于找出谜语是什么，这里有一个解释

下一个数字是上一个数字中的字母数。因此，例如，五个有四个字母，因此下一个数字是四个。

六个有三个字母，所以下一个数字是3，三个有五个字母，所以下一个数字是5，五个有四个字母，所以下一个数字是4

谜题以4结尾的原因是因为四个有四个字母，四个是四个，四个是四个，四个是四个...（四个是魔幻数字）

测试用例

999,999 =>
  Nine Hundred Ninety Nine Thousand Nine Hundred Ninety Nine is fifty and fifty is five and five is four and four is the magic number

规则

  • 输入可以取自STDIN函数或可以作为函数的参数
  • 输入为0到999,999之间的正数
  • 输入将仅包含数字（它将遵循regex ^[0-9]+$）
  • 输入可以是整数或字符串
  • 当转换为字串时，计数中不应包含空格和连字符（100 [一百]是10个字符，而不是11。1,742 [一千七百四十二]是31个字符，而不是36）
  • 当转换为字符串时，100应该是一百，而不是一百或一百，1000应该是一千，而不是一千或一千。
  • 当转换为字符串142应该是一百四两个，而不是一百和四十二
  • 输出不区分大小写，并且应遵循以下格式：“ N是K，K是M，M是...，并且四是幻数”（除非输入为4，在这种情况下，输出应为“四”是魔术数字”）
  • 只要您的程序始终一致，输出就可以使用数字而不是字母（“ 5是4，4是幻数”而不是“ 5是4和4是幻数”）
  • 输出可以是函数的返回值，也可以打印为 STDOUT
  • 适用标准漏洞
  • 这是代码高尔夫球，因此以字节为单位的最短程序获胜。祝好运！

奖金

如果程序在输入介于-999,999和999,999之间时工作，则为-30个字节。

负数转换为单词时，在其前面仅带有“负数”。例如-4“负四”，负四是十二，十二是六，六是三，三是五，五是四，四是魔数

-150字节（如果程序未使用任何内置函数来生成数字的字符串表示形式）

排行榜

for((n=$1;n-4;n=m)){
m=`number -l -- $n|sed 's/nus/&&/;s/\W//g'`

受到Cole Cameron的回答的启发。我以为没有宏定义，我也许可以做得更好。尽管我最终做到了，但确实需要花些力气才能实现！

它需要一个带有连续字母的主机字符集（因此ASCII可以，但是EBCDIC将不起作用）。这是用于一对查找表的。我选择j了零字符，并且利用了需要进行两次查找的优势，因此我可以从另一个中减去一个，而不必从两个中都减去我的零。

评论版本：

char*i=
    "jmmonnmoon"                /* 0 to 9 */
    "mpprrqqsrr"                /* 10 to 19 */
    "jjddeeecdd";               /* tens */
char x;                /* current letter count */

f(n,c){
return
    !n?n                        /* zero - return 0 (ignore c) */
    :n<0?f(-n,8)                /* negative n (only reached if c==0) */
    :n<100?c+i[n<20?n:n%10]-i[20+n/10] /* lookup tables */
    :
      f(n/1000,8)               /* thousand */
    + f(n/100%10,7)             /* hundred */
    + f(n%100,0)                /* rest */
    + c;                        /* carry-in */
}
main(int c, char**v)
{
    for(c=atoi(*++v);c-4;c=x)
        printf("%d is %d and ",c,x=c?f(c,0):4);
    puts("4 is the magic number");
}

通过替换f(n/1000,8)为，显然可以扩展支持数百万美元f(n/1000000,7)+f(n/1000%1000,8)。

如果Swift的正则表达式不是那么冗长（除去连字符和空格），我将能够摆脱176个字节。

func c(var s:Int)->String{var r="";while(s != 4){r+="\(s)";let f=NSNumberFormatter();f.numberStyle=NSNumberFormatterStyle.SpellOutStyle;let v=f.stringFromNumber(s)!;s=v.stringByReplacingOccurrencesOfString("[- ]",withString:"",options:NSStringCompareOptions.RegularExpressionSearch,range:Range<String.Index>(start:v.startIndex,end:v.endIndex)).utf8.count+(s<0 ?3:0);r+=" is \(s) and "};return r+"4 is the magic number"}

Haskell，285-180 = 105字节

实际上，根本没有内置的数字显示功能。我仍然对分数不满意。随时发表评论。不过，我将进一步尝试。分数仍然比Swift的分数好

c n|n<0=8+c(-n)|n>999=r 1000+8|n>99=7+r 100|n>19=r 10+2-g[30..59]+g[20..29]|n>15=r 10-1|2>1=[0,3,3,5,4,4,3,5,5,4,3,6,6,8,8,7]!!n where{g=fromEnum.elem n;r k=c(mod n k)+c(div n k)}
m 4="4 is the magic number"
m 0="0 is 4 and "++m 4
m n=show n++" is "++show(c n)++" and "++m(c n)

用法

m 7
"7 is 5 and 5 is 4 and 4 is the magic number"
m 999999
"999999 is 50 and 50 is 5 and 5 is 4 and 4 is the magic number"

说明。

m是微不足道的，但是，事实c并非如此。c是计算字符数的函数，数字的英文名称为。

c n |n<0=8+c(-n) -- Add word "negative" in front of it, the length is 8
    |n>999=r 1000+8 -- the english name for number with form xxx,yyy is xxx thousand yyy

Python 641-150 = 501字节

至少它不比Java长！它基于此，除了使用字符串。

编辑：我忘了约0，我需要说“ 5是4”，而不是跳到“ 4是魔术数”-这增加了分数。 

w={0:"zero",1:"one",2:"two",3:"three",4:"four",5:"five",6:"six",7:"seven",8:"eight",9:"nine",10:"ten",11:"eleven",12:"twelve",13:"thirteen",14:"fourteen",15:"fifteen",16:"sixteen",17:"seventeen",18:"eighteen",19:"nineteen",20:"twenty",30:"thirty",40:"forty",50:"fifty",60:"sixty",70:"seventy",80:"eighty",90:"ninety"}
s=""
def i(n):
 global s
 e=""
 o=n%10
 t=n%100
 h=n/100%10
 th=n/1000
 if th:
  e+=i(th)
  e+='thousand'
 if h:
  e+=w[h]
  e+='hundred'
 if t:
  if t<20 or o==0:
   e+=w[t]
  else:
   e+=w[t-o]
   e+=w[o]
 if len(e)==4:s+="4 is the magic number";print s
 else: s+="%d is %d and "%(n,len(e));i(len(e))
In=input()
i(In)

在这里尝试！

您不必显示名称，对不对？

这是不正确的。i(5)打印4 is the magic number，而不是5 is 4 and 4 is the magic number。

MOO，182 176/ 192个 188个字节- 30 =158分之146

188字节版本：

u=$string_utils;s="";i=args[0];while(i-4)j=u:english_number(i);s=s+j+(s?" and "+j|"")+" is ";i=length(u:strip_chars(j,"- "}));endwhile;return s+(s?"four and "|"")+"four is the magic number"

176个字节的实现相关版本：

s="";i=args[0];while(i-4)j=#20:english_number(i);s=s+j+(s?" and "+j|"")+" is ";i=length(#20:strip_chars(j," -"));endwhile;return s+(s?"four and "|"")+"four is the magic number"

两者都是功能。

PHP，168-30 = 138个字节

function m($i){$e=strlen(preg_replace('/[^a-z-]/','',(new NumberFormatter("en",5))->format($i)));echo($i==$e?"":"$i is $e and "),($e==4?"4 is the magic number":m($e));}
