代码高尔夫7月版第4期:计算前十个发生的单词

鉴于以下总统名单可以在最小的计划中进行前十个字数:

    Obama

以bash 97个字符开始

cat input.txt | tr " " "\n" | tr -d "\t " | sed 's/^$//g' | sort | uniq -c | sort -n | tail -n 10

输出:

      2 Nixon
      2 Reagan
      2 Roosevelt
      2 Truman
      2 Washington
      2 Wilson
      3 Bush
      3 Johnson
      4 FDR
      7 DIES

如你所愿打破关系!快乐第四!

对于那些关心总统的人来说,可以在这里找到.

C#,153:

读入文件p并将结果打印到控制台:

File.ReadLines(p)
    .SelectMany(s=>s.Split(' '))
    .GroupBy(w=>w)
    .OrderBy(g=>-g.Count())
    .Take(10)
    .ToList()
    .ForEach(g=>Console.WriteLine(g.Count()+"|"+g.Key));

如果仅生成列表但不打印到控制台,则为93个字符.

6|DIES
4|FDR
3|Johnson
3|Bush
2|Washington
2|Adams
2|Jefferson
2|Madison
2|Monroe
2|Jackson

较短的shell版本:

xargs -n1 < input.txt | sort | uniq -c | sort -nr | head

如果您想要不区分大小写的排名,请更改uniq -c为uniq -ci.

稍微短一点,如果你对排名被逆转感到高兴,可读性因缺乏空间而受损.这个时钟有46个字符:

xargs -n1

(如果允许您首先将输入文件重命名为"i",则可以将其删除为38.)

观察到,在这种特殊情况下,没有任何单词出现超过9次,我们可以通过从最终排序中删除'-n'参数来减少3个字符:

xargs -n1

这将此解决方案降低到43个字符,而无需重命名输入文件.(或35,如果你这样做.)

使用xargs -n1将文件拆分为每行上的一个单词比tr \  \\n解决方案更可取,因为这会产生大量空白行.这意味着该解决方案不正确,因为它错过了Nixon并显示一个显示256次的空白字符串.但是,空字符串不是"单词".

        

3> ojblass..：
vim 60 

    :1,$!tr " " "\n"|tr -d "\t "|sort|uniq -c|sort -n|tail -n 10

        

4> Josef Pflege..：
Vim 36

:%s/\W/\r/g|%!sort|uniq -c|sort|tail

        
你可以丢失4个字符,因为'tail'相当于'tail -10'或'tail -n10'. 

5> ephemient..：
Haskell,102个字符(哇,非常接近原始版本):

import List
(take 10.map snd.sort.map(\(x:y)->(-length y,x)).group.sort.words)`fmap`readFile"input.txt"


J,只有55个字符:

10{.\:~~.(,.~[:<"0@(+/)=/~);;:&.><;._2[1!:1<'input.txt'


(我还没弄清楚如何在J中优雅地执行文本操作......它在数组结构数据方面要好得多.)
