代码高尔夫:钢琴

发布于 2024-08-20 03:36:07 字数 1576 浏览 8 评论 0原文

挑战

按字符数计算的最短代码,用于输出从给定长度的输入音符开始的钢琴键盘的一部分。

输入将由开始打印键盘的注释 ([ACDFG]#|[AG]) 和表示要打印的键长度(包括第一个注释)的正数组成。

第一个键应该完整打印 - 如果它有左锐键,它将被剪切,同样,当开始键是锐键时,左键也会被剪切。

夏普键不计算在内,只计算白键。

代码计数包括输入/​​输出(即完整程序)。

The challenge

The shortest code by character count to output a part of a piano keyboard starting from input note in a given length.

Input will be composed of a note ([ACDFG]#|[A-G]) to start printing the keyboard from and a positive number representing length of keys to print including the first note.

The first key should be printed in full - if it has a left sharp key, it will be cut, same for when the start key is sharp, the left key will be cut as well.

A Sharp key is not counted, only white keys.

Perl,133 (129) 字符

Perl,167 160 156 147 142 < Strike>133 哦! 147 144 137 134 133 个字符

    $_=shift;die grep{5>$n?y/*/#/:y/#*/ |/;$n++-8||y/ /_/}
    @Q=(substr(("*#  #".("*#  #*#   |   #")x2)x9,
    4*/#/+(7&ord)*5,1+/#/+5*pop).$/)x9

这是一个 129 个字符的解决方案,借鉴了 molf 的 Ruby 解决方案的几个想法

    ($_,$c)=@ARGV;$j=($k=/#/)+ord;
    for$n(0..8){print$/,substr+(join'',map{8-$n?5>$n&&$_%7%4?"###  "
    :" |   ":"_|___"}$j..$j+$c),!$k,-3}

:来自 Acme::AsciiArtinator 的帮助:

                sub init_piano{$S=$";$H='#';
                (                            $

Perl, 133 (129) chars

Perl, 167 160 156 147 142 133 D'oh! 147 144 137 134 133 chars

    @Q=(substr(("*#  #".("*#  #*#   |   #")x2)x9,
    4*/#/+(7&ord)*5,1+/#/+5*pop).$/)x9

Here's a 129 char solution, borrowing several ideas from molf's Ruby solution:

    ($_,$c)=@ARGV;$j=($k=/#/)+ord;
    for$n(0..8){print$/,substr+(join'',map{8-$n?5>$n&&$_%7%4?"###  "

Ruby - 125 个字符

146 144 140 137 134 126 Strike> 125 个字符

a,n=$*;h=a[1]?0:1;s=a[0]-h+1
9.times{|t|puts (s..s+n.to_i).map{|i|i%7%4<1||t>4?" |   ":"###  "
}.join[h..-4].tr t>7?" ":n,"_"}

(第二个换行符不是必需的,添加只是为了避免 SO 上出现滚动条。如果需要,可以用换行符替换分号。)

Ruby 1.9 版本不同,但长度相同(将 a[0] 替换为 a.ord 并将 "_" 替换为 ?_):

a,n=$*;h=a[1]?0:1;s=a.ord-h+1
9.times{|t|puts (s..s+n.to_i).map{|i|i%7%4<1||t>4?" |   ":"###  "

I persist to golf in C# although it's not a very terse language...

为什么只使用 C 或当您可以使用完整的 Octave 进行编程时,使用 C# 或 F#(或 B 或 D)?

(为了清楚起见,每 60 个字符换行一次)

x=5*scanf("%2c%d");for k=-8:0disp((s={[t="|   ###  ###  ","#
##   ",t" "]"|    ","|____"}{(k>-4)+!k+1})(1+mod(5*(y=x(2)>1
60)+(-y:x(3))+x(1),rows(s'))))end

是的......这个解决方案确实计算了字符串的复共轭转置。

用法:$octave -q thisfile.moutput.out

Octave, 153 154 155 158 159 162 172 180 186 185 188 197 199 200 206 207 209 212 214 215 219 240 244 268 characters

Why use just C or C# or F# (or B or D) when you can program with a full Octave?

(wrapped every 60 chars for clarity)

x=5*scanf("%2c%d");for k=-8:0disp((s={[t="|   ###  ###  ","#
##   ",t" "]"|    ","|____"}{(k>-4)+!k+1})(1+mod(5*(y=x(2)>1
60)+(-y:x(3))+x(1),rows(s'))))end

Yes ... this solution really does compute the complex conjugate transpose of a string.

Usage: $ octave -q thisfile.m <input.in >output.out

This equivalent 194-character version assumes buffer overflow is fine.

g"|   ###  ###   |   ###  ###  ###   "5 
g"|    "3
g"|____"1

我使用 2 的模块来检测空格或井号。
' ' 为 32 % 2 = 0
“#”为 35% 2 = 1
由于我的条件返回 false 零,所以我只是将模块结果相乘。

使用了<|运算符删除一个空格字符。
使用运算符重载来保存另一个字符。

原来的

let piano_long (input:string) = 
    let sharp, flat = if input.[1] = '#' then 4, 1 else 0, 0

    let note = (int input.[0] - 60) % 7
    let num = int (input.Substring 2)

    let start = note * 5 + sharp
    let stop = num * 5 + 1 + flat

    let top    = "|   ###  ###   |   ###  ###  ###   |   ###  ###   |   ###  ###  ###   |"
    let middle = "|    |    |    |    |    |    |    |    |    |    |    |    |    |    |"
    let bottom = "|____|____|____|____|____|____|____|____|____|____|____|____|____|____|"


    let mutable piano = ""

    for i in 1..5 do 
        piano <- piano + top.Substring(start, stop) + "\n"

    for i in 1..3 do 
        piano <- piano + middle.Substring(start, stop) + "\n"

    piano <- piano + bottom.Substring(start, stop)

    printf "%s\n\n" piano

g"|   ###  ###   |   ###  ###  ###   "5 
g"|    "3
g"|____"1

I used modules of 2 to detect for a space or pound.
' ' is 32 % 2 = 0
'#' is 35 % 2 = 1
and since my conditional returned zeros for false I just multiplied the modules result.

Used the <| operator to shave off one space char.
Used operator overloading to save another char.

Works for up to 99 keys. The standard piano has 52 white keys, so this should be sufficient.

必须改进。

输入必须在名为 PIANO 的常量中传递。

Shall have to be improved.

The input has to be delivered in the constant named PIANO.

F# 414 386 372 重要字符:

//wins me 2 characters
open System

//String.replicate, didn't know this existed before reading Juliet
let r=String.replicate  

//print s n times, each time on a newline
let P n s=printf"%s"(r n (s+"\n"))  

//define top rows
let t="##  ###   |   ###  ###   |   ###  #" 

//middle and bottom rows can be defined using 'r'
let m,b=r 7"|    ",r 7"|____" 

//pick of chars from O to n+O from string, wrap round if we go beyond s.Length
let L(s:string)O n=String([|5*O..5*(n+O)|]|>Array.map(fun i->s.[i%35]))

//match input string into two halves
let[|k;n|]=Console.ReadLine().Split([|' '|])

//work out start pos and length (in chars, not keys)
let O,N=
 let K=int k.[0]-65                    //'A'=65, this is why t starts at A
 if k.[0]='#'then(K+3,int n+2)else(K,int n) 

//Print 5 top rows, 3 middle rows and the bottom row
P 5(L t O N)
P 3(L m O N)
P 1(L b O N)

哦,还有一个好处,这个脚本实际上可以正确处理“F# 372” - 我不会惹恼不过,您可以将其粘贴到此处...

System.Console.ReadLine() 真是太糟糕了...

Oh, and one bonus, this script will actually handle "F# 372" correctly - I won't annoy you by pasting it here though...

System.Console.ReadLine() is such a bummer...
