# Produce the word 'codegolf' without using any of its characters in code [closed]

You need to produce the word codegolf

### Rules:

1. None of the characters of the word codegolf (i.e. 'c', 'o', 'd', 'e', 'g', 'o', 'l' and 'f') in either case can exist anywhere in the code.

2. Case of the word must be one of three:

• All Upcase (CODEGOLF)
• All Downcase (codegolf)
• Capitalized (Codegolf)
3. You only need to produce it somehow so there can be other characters in the output as well. For example, 21§HCodegolf092 is an acceptable result.

4. The shortest code (counting in bytes) to do so in any language wins.

I guess it will be less trickier in some languages than others (Brainfuck, Javascript, etc.)

• Why the downvotes? – Sheharyar Dec 14 '14 at 6:30
• The downvotes are probably because "print X without X" is a type of challenge that's been done to death and people are tired of it. So, it's not your question but the site's history, which I can't blame you for not knowing. – xnor Dec 14 '14 at 6:34

## Bash(works if there are no other files matching /bin/?at), 14

/bin/?at /*/u*


This expands to cat <files>, where the files include /dev/urandom. Because of the infinite monkey theorem, this will eventually output "codegolf".

# C - lots of characters

Without include, define, char, printf, return and lots of other useful things, it's a real challenge to try to do this in C.

I thought of outputting upside down letters, i.e. ɟloƃǝpoɔ, but the l and o are the same.

So here's the best I can do, which many people might remember as being very much like their first C assignment.

int main()
{
puts("                   @                       @     @@ ");
puts("                   @                       @    @   ");
puts("                   @                       @    @   ");
puts("  @@@    @@@    @@@@   @@@    @@@@   @@@   @  @@@@@ ");
puts(" @   @  @   @  @   @  @   @  @   @  @   @  @    @   ");
puts(" @      @   @  @   @  @@@@@  @   @  @   @  @    @   ");
puts(" @   @  @   @  @   @  @      @   @  @   @  @    @   ");
puts("  @@@    @@@    @@@@   @@@    @@@@   @@@   @    @   ");
puts("                                 @                  ");
puts("                                 @                  ");
puts("                              @@@                   ");
}


To compile: gcc -o codegolf codegolf.c, surprisingly gcc, at least my installation, doesn't complain about missing includes or returns.

Running:

## PHP, 13 bytes

<?=~œ›š˜“™;


StackExchange may swallow some of the control characters. Here's a hexdump of the program:

3c 3f 3d 7e 9c 90 9b 9a 98 90 93 99 3b


It bitwise inverts the string, and prints it using the PHP short tag syntax.

# Pyth, 9 bytes with updated rules

^v"\107"8


v"\107" evals a string containing G, octal escaped, which is the pyth variable for the alphabet.

^G8, is the result, which prints all 8 letter strings in the lowercase alphabet, including codegolf. Runs out of memory on my machine, unfortunately.

• Unfortunately, this uses the now-banned capital G. What bad luck with your choice of Pyth's letters! – xnor Dec 14 '14 at 9:02
• @xnor Fixed. Only tripled the length. – isaacg Dec 14 '14 at 10:58
• This answer inspires me to suggest a new Pyth constant: A fixed, extremely long string of random characters. Or a De Brujin graph if you want to be efficient. – xnor Dec 14 '14 at 11:01
• @xnor Would that help for any non trivial challenges? – isaacg Dec 14 '14 at 11:03
• Not really, I'm just amused at the idea of one-character solutions. Unless iterating over it saves chars when you want to do something a huge but finite number of times? – xnor Dec 14 '14 at 11:06

I guess it should be shorter than Marbelous.

# Java, 118 Bytes

This is probably the lamest answer. Java programs have many key words. In order to print anything you have to use System.out. Despite all of these restrictions I can remove all of the letters in codegolf from my program except two letters.

With c and o allowed, 118 bytes:

c\u006cass a{pub\u006cic static voi\u0064 main(String[]a){Syst\u0065m.out.print("\143\157\144\145\143\157\154\146");}}


With l and o allowed, 123 bytes:

\u0063lass a{publi\u0063 stati\u0063 voi\u0064 main(String[]a){Syst\u0065m.out.print("\143\157\144\145\143\157\154\146");}}


With c and f allowed, 128 bytes:

c\u006cass a{pub\u006cic static v\u006fi\u0064 main(String[]a){Syst\u0065m.\u006fut.print("\143\157\144\145\143\157\154\146");}}


With l and f allowed, 133 bytes:

With no restrictions on boilerplate code, 98 bytes:

class a{public static void main(String[]a){System.out.print("\143\157\144\145\143\157\154\146");}}


Expanded:

class a{

public static void main(String[]a){
System.out.print("\143\157\144\145\143\157\154\146");
}

}

It runs very slowly, and it should run out of memory on most computers. But if it exited successfully finally, it will print a lot of things including CODEGOLF.

# C, 49 bytes

main(){int a[3]={1701080931,1718382439};puts(a);}


# C11, 46 bytes

main(){puts((int[3]){1701080931,1718382439});}


It's obviously possible in C.

Works in 32bit little-endian systems.

# Marbelous - 9 bytes

7A
/\/\??


This will with a probability approaching 1 print a string containing all three acceptable outputs, since it prints an endless string of random ascii characters (up to and including the lowercase 'z' with ascii value 7A). Nothing was specified about whether this program should terminate. And just to make it clear, the characters get printed as they get generated, not after the program terminates (which is never).

This answer creates a format string using a 'c' found in the representation string of the built-in map function. The program then uses the format string to convert each integer into a character that creates the 'CODEGOLF' string.

You can try it out here (Replace the code in the code() function with this code).

If it is acceptable, the final semicolon can be removed and the program will loop infinitely (in theory, not in the interpreter, as the interpreter gives up after 2048 instructions to avoid a browser-crashing infinite loop) for a score of 25 bytes.

This works by pushing the values for the characters CODEGOLF to the stack, printing them, and terminating.
