선택한 두 가지 언어를 사용하여 할 수 있는 가장 작은 "상호 퀴인 "을 작성하십시오 .

즉, 프로그램 Q의 출력이 P의 소스 코드와 동일하도록 언어 B의 프로그램 Q에 대한 소스 코드를 출력하는 프로그램 A를 언어 A로 작성하십시오.

빈 파일은 계산되지 않으며 "소스 파일을 읽고 인쇄"스타일의 프로그램도 포함하지 않습니다.

편집 : P = Q 인 답변은 더 이상 계산되지 않습니다.

"00gr00g:a9*2+$' tnirp'>o<

이 파이썬을 생성합니다

print "\"00gr00g:a9*2+$' tnirp'>o<"

파이썬과 루비, 39 자

이 파이썬 스 니펫

s='puts %%q{s=%r;print s%%s}';print s%s

이 루비 스 니펫을 생성합니다

puts %q{s='puts %%q{s=%r;print s%%s}';print s%s}

그런 다음 초기 Python 스 니펫을 다시 생성합니다.

$ diff -s mutualquine.py <(ruby <(python mutualquine.py))
Files mutualquine.py and /dev/fd/63 are identical

이것은 JB의 답변 과 유사합니다 .

C와 펄, 73

이 C :

main(s){printf(s="print q<main(s){printf(s=%c%s%c,34,s,34);}>",34,s,34);}

... 다음 Perl을 출력합니다 :

print q<main(s){printf(s="print q<main(s){printf(s=%c%s%c,34,s,34);}>",34,s,34);}>

... C를 다시 출력합니다.

C 및 C ++, 123 자

이 C (gcc v4.3.4로 컴파일 가능) :

#include <stdio.h>
main(){char *c="#include <stdio.h>%cmain(){char *c=%c%s%c;printf(c,10,34,c,34);}";printf(c,10,34,c,34);}

이 (동일한) C ++ (g ++ 4.3.4로 컴파일 가능, 하나의 경고)을 출력합니다.

#include <stdio.h>
main(){char *c="#include <stdio.h>%cmain(){char *c=%c%s%c;printf(c,10,34,c,34);}";printf(c,10,34,c,34);}

이것은 게시 된 규칙 내에 있습니다. : P 그리고 Ventero와 마찬가지로 이것은 JB의 답변을 기반으로 합니다.

자바에서 파이썬으로-219

자바:

class Q{public static void main(String[]a){char q=34,c=39;String s="print%sclass Q{public static void main(String[]a){char q=34,c=39;String s=%s%s%s;System.out.printf(s,c,q,s,q,c);}}%s";System.out.printf(s,c,q,s,q,c);}}

파이썬 :

print'class Q{public static void main(String[]a){char q=34,c=39;String s="print%sclass Q{public static void main(String[]a){char q=34,c=39;String s=%s%s%s;System.out.printf(s,c,q,s,q,c);}}%s";System.out.printf(s,c,q,s,q,c);}}'

파이썬 '이 문자열을 허용한다는 사실을 이용합니다 . 이것은 파이썬 프로그램에서 자바 프로그램의 소스를 작성하는 것을 훨씬 쉽게 만듭니다.

Python + Piet one- liners : 417 문자 + 7391 7107 코덱 실행

이 Python 스크립트는 7393 x 2 이미지를 생성합니다. 가장 오른쪽의 2x2 블록은 프로그램을 종료하는 "센티넬"입니다. 그래서 나는 그것들을 세지 않습니다. 두 번째 줄은 그렇지 않으면 흰색입니다. 순진 이진 알고리즘 대신 더하기 / 빼기 / 곱셈 체인을 사용하여 피에트 코드를 더 많이 사용할 수 있지만 미래의 퍼즐에 대한 해결책을 제시하고 싶지 않습니다.

이미지의 크기 때문에 여기에 이미지를 게시하지 않겠습니다. 그것을 보려면 파이썬 코드를 실행하고 출력을 .ppm 파일로 파이프하십시오. 그 다음, .gif 참고로 .ppm을 변환하고,에서 출력 실행 Rapapaing을 . (또는 .ppm을 움켜 쥐는 웹이 아닌 Piet 인터프리터를 사용하십시오)

A='P=lambda A:reduce(lambda(D,H,B),P:(D[P/3:]+D[:P/3],H[P%3*2:]+H[:P%3*2],B+"".join("%i "%H[(D[0]/P)%2]for P in[1,2,4])),map(" A !        @    B".find,A),([1,3,2,6,4,5],[0,192,192,255,0,255],"P3 %i 2 255 "%(len(A)+2)))[2]+"255 "*4+"0 0 "+"255 "*len(A)*3+"255 0 0 "*2;B=lambda D:["@!%s","@@!%s!"][D%2]%B(D/2)if 1<D else"";print P("".join("A%sB"%B(ord(D))for D in"A=%s;exec A[:-13]"%`A`)+" ");exec A[:-13]';exec A[:-13]

편집 : 변수 이름의 해밍 무게를 줄임으로써 피에트를 조금 골프 쳤다.

덜 골프 프리 퀸 :

이것은 이전 버전으로, 하나의 라이너로 만들 수 있다는 것을 깨달았습니다. 이해하기가 조금 더 쉽습니다. 함수 P는 특수 명령어 세트를 Piet으로 변환합니다. 함수 p는 정수를 취하여 스택에 해당 정수를 생성하는 명령 시퀀스를 생성합니다. 나는 단지 instructions 만 사용하고 =,+,:,|있기 때문에 아마도 더 효율적으로 만들 수는 있지만 ... 소스에 완전한 종류의 Piet 컴파일러가있는 것과 같습니다.

s="""def P(s):
 l=len(s)+1;R="P3 %i 2 255 "%(l+2);C=[1,3,2,6,4,5];V=[0,192,192,255,0,255]

루비와 파이썬 (393 + 413 = 806 자)

이 대답 의 약간의 변화 . 최적화없이 입력을 하드 코딩했기 때문에 분명히 감소 할 수 있습니다.

루비 (393 자)

require 'json';s=%q[{"ruby":[" %q[","require 'json';s=##;j=JSON.load s;puts j[l='python'][1].sub('##',j[l][0].delete(' ')+s+j[l][2].delete(' '))"," ]"],"python":["' ''","import json,re;s=##;j=json.loads(s);l='ruby';print(re.sub('##',j[l][0].replace(' ','')+s+j[l][2].replace(' ',''),j[l][1],1))","' ''"]}];j=JSON.load s;puts j[l='python'][1].sub('##',j[l][0].delete(' ')+s+j[l][2].delete(' '))

파이썬 (413 자)

import json,re;s='''{"ruby":[" %q[","require 'json';s=##;j=JSON.load s;puts j[l='python'][1].sub('##',j[l][0].delete(' ')+s+j[l][2].delete(' '))"," ]"],"python":["' ''","import json,re;s=##;j=json.loads(s);l='ruby';print(re.sub('##',j[l][0].replace(' ','')+s+j[l][2].replace(' ',''),j[l][1],1))","' ''"]}''';j=json.loads(s);l='ruby';print(re.sub('##',j[l][0].replace(' ','')+s+j[l][2].replace(' ',''),j[l][1],1))

Python 2에서 Befunge로 98, 94 78

다시 말하지만, 파이썬의 문자열을 만드는 두 가지 방법을 사용합니다

파이썬 :

s='<@,kM%c%cs=%c%s%c;print s%%(39,34,39,s,39,34)%c';print s%(39,34,39,s,39,34)

펀지 98 :

<@,kM'"s='<@,kM%c%cs=%c%s%c;print s%%(39,34,39,s,39,34)%c';print s%(39,34,39,s,39,34)"

파이썬 프로그램은 문자열 자체를 포함하고 작은 따옴표와 큰 따옴표의 문자를 포함하도록 문자열을 형식화합니다.

Befunge 프로그램은 다음과 같이 작동합니다.

• <: 왼쪽으로 이동하고 둘러 쌉니다. 이제 오른쪽에서 왼쪽으로 명령을 실행합니다

• ": 발생하는 모든 문자가 다른 문자를 만날 때까지 스택으로 "푸시되도록 다음과 같이 푸시합니다.

  )43,93,s,93,43,93(%s tnirp;'c%)43,93,s,93,43,93(%%s tnirp;c%s%c%=sc%c%Mk,@<'=s
  

  이것은 실제로 파이썬 프로그램 일뿐이며 Befunge가 인쇄하는 방식 (팝 + 인쇄 루프)으로 인해 반전되었습니다.

• 'M: M스택으로 밀어 넣 습니다. M또한 숫자 77은 "s에 의해 스택에 푸시 된 문자 수보다 1이 적습니다 .
• k: 스택에서 최상위 값을 꺼내고 ( M) 다음 작업에 여러 번 더하기 1을 더합니다.
• ,: 스택에서 최상위 값을 팝하고 문자를 인쇄합니다.
• @: 프로그램을 종료합니다.

언더로드 및 베타로드 , 16 바이트 (비경쟁)

언더로드 :

(a(:^)*a(S)*S):^

베타로드 :

((a(:^)*a(S)*S):^)S

Betaload는 Underload의 상위 집합이므로 두 가지 Underload 답변이 될 수 있습니다.

이 챌린지가 게시 된 후 Betaload가 생성되었으므로 경쟁이 아닙니다.

클리퍼 및 C (111 + 108 = 219 자)

클리퍼 (111)

?'char*f="%c%cchar*f=%c%s%c;main(){printf(f,63,39,34,f,34,39,10);}%c%c";main(){printf(f,63,39,34,f,34,39,10);}'

C (108)

char*f="%c%cchar*f=%c%s%c;main(){printf(f,63,39,34,f,34,39,10);}%c%c";main(){printf(f,63,39,34,f,34,39,10);}

다음과 같은 이유로 약간의 cop-out입니다.

1. Clipper의 "print"명령은 정말 간단합니다 : ?'foo':-)
2. 나는 http://www.nyx.net/~gthompso/quine.htm 의 "클래식 C"퀴네를 기반 으로했고 ?, 's 를 쥐어 짜기 위해 약간 수정했습니다 .
3. 나는하지 않았 #include <stdio.h>으므로 컴파일러에게 경고를줍니다.
4. Clipper 버전의 C 코드 출력은 터미널이나 Harbor 인쇄 루틴 또는 기타에서 80 자 열 제한에 의해 도입 된 줄 바꿈을 제거하기 위해 자극되었습니다.

파이썬과 ~-~! -77과 81 = 158

이 파이썬 코드 :

q=chr(124);s='@%sq=chr(124);s=%s;print(s%%repr(s))%s:';print(s%(q,repr(s),q))

이것을 ~-~! 암호:

@|q=chr(124);s='@%sq=chr(124);s=%s;print(s%%repr(s))%s:';print(s%(q,repr(s),q))|:

확실히 많이 향상 될 수 있으며 다른 답변에서 전체 무리를 채택합니다.
