Print X without X (robber's thread)

Question

This is the robber's thread of a cops-and-robbers challenge. You can view the cop's thread here

A pretty common beginner style question is to print some string, but, there's a catch!, you need to do it without using any of the characters in the string itself!

For this challenge we will find out who is the best at printing X without X. There are two threads to this, a cop's thread and a robber's thread.

In the cop's thread users will choose a language (which we will call Y) and a string (which we will call X) and write a program in language Y which takes no input and outputs X without using any of the characters in X. The cop will then post both X and Y without revealing the program they have written.

Robbers will be select cop answers and write programs in language Y which take no input and output X. They will post these "cracks" as answers in this thread. A crack need only work not be the intended solution.

Once a cop's answer is one week old, so long as it has not been cracked, the cop may reveal their program and mark it as "safe". Safe answers can no longer be cracked

Robbers will be scored by the total number of successful cracks with more cracks being better.

Explanation: First, we can immediately figure out what builtins we have available to us with the following snippet:

for b in dir(__builtins__):
  if not any(c in b for c in "cdnsvw,"):
    print(b)

Of immediate interest is getattr. My original approach used this along with eval, but then I realized that v was banned... (c is also banned so no exec). In any case, as long as we can get arbitrary characters and we have getattr, it's game over. Of course, no c, so no chr, so how do we get arbitrary letters? Indexing into dir() is out too, because we don't have access to d.

Well, Python 2 has this neat trick where you can decode hex strings by simply doing str.decode("hex"). "decode" requires both "c" and "d", so we need to get those characters first, but fortunately they're hex digits, so we can just retrieve them with "%x"%12 and "%x"%13, respectively (Note: the reason we can do this here, but not to get dir is because decode is an attribute of strings, which we can get, whereas dir is an attribute of __builtins__, which we can't get because of the s).

The last trick is to evade , in our getattr calls, which we can do by using arg expansion on a list, which we construct by adding lists together: getattr(a,b) <=> getattr(*([a]+[b])). From here we just chain together these primitives. Translated, the answer looks like:

__import__("sys").stdout.write("63646e7376772".decode("hex"))

Answer 2

Java, cracks MCross's answer

class Puzzle {
  public static void main(String[] args) throws Throwable {
    try (AutoCloseable a = new Throwable() {
        {
            setStackTrace(new StackTraceElement[0]);
        }
        @Override
        public String toString() {
            return "" + (char)(46) + (char)(92);
        }
    }::printStackTrace) {}    
  }
}

All the credit goes to @nthistle, who found this resource, which I shamelessly copied.

It uses a method reference to override AutoCloseable's close method, which gets invoked at the end of a try-with-resources block. The toString method contains the actual message, and the setStackTrace part ensures it doesn't print the actual stacktrace afterwards.

No numbers? No problem! Also, note the suspicious lack of C and S in the output string. This immediately clued me in to String.fromCharCode – the only problem is how to produce numbers, since all number literals are banned. Fortunately, JavaScript has some really awful type juggling, so you can produce the number 3, for instance, like (+!+[])+(+!+[])+(+!+[]).

In practice, as long as ()+[]! are all allowed, you can just use JSFuck to convert the whole thing, but it really inflates the size (the version of my answer wouldn't fit in this post), and no C and S made me assume that String.fromCharCode was the intended solution anyways. I did borrow the literals for 1 and 10 in order to construct my character codes, though.

Looking at the character set, we can call eval and we have the + operator to concatenate strings. So if we can build arbitrary one-character strings, we're done. In Ruby, creating a character from its numeric code is 123.chr, but we don't have . or c.

I browsed through the list of global variables and predefined functions to see what interesting things I could use given the available characters.

We don't have digits, but since we have arithmetic operators, that's just a minor annoyance. We create variables containing each digit as a string, for later.

Our next objective is to have a way to extract a specific character from a string, without the […] subscript operator. Almost every interesting action on a string is a (non-operator) method call, which is impossible without .. We can do regexp matching. string =~ /./ puts the first character of the string in $&, and string =~ /.$/ puts the last character in $&, but we don't have .. Let's build ..

We can take a floating point number and convert it to a string with String. But we still don't know how to extract the . from that string. There's another way to match a single character in a regexp without simply listing this character, and that's character sets: can we somehow inject [something.somethingelse] into the regexp? Yes! We can inject the value of an expression (converted to a string) with /#{expression}/. And we can build a string surrounded by brackets by building an array, which is represented as [element, ...] as a string. Match "2.0" against /[1.0]/, and we get "." in $&. Now we can extract an arbitrary character from a string with one or two regexp matches (/#{DOT}…#{DOT}/ then /#{DOT}$/ to take the Nth character, or /#{DOT}…#{DOT}$/ then /#{DOT}/ to take the Nth character from the end).

Our next objective is to construct the string ".chr", after which we can construct arbitrary characters as e.g. eval "1" + "2" + "3" + ".chr". We can have hr in the source code but we need to inject them into a string, and we need to get chr from somewhere. A convenient way to inject letters into a string is global_variables, which converts to a string that looks like

[…, :$alakazam_hrto_s, …]

So define a global variable containing hr, add a unique pattern (alakazam_) to anchor it, and match /alakazam_../ against String global_variables. While we're at it, use regexp matching to get ":" and " ", and also "to_s". We can now evaluate "12.to_s 16" to get "c" (hexadecimal representation of 12).

Now that DOT_CHR is ".chr", assemble f_out = "putc", and print the desired characters one by one given their numeric code.

Forming digits is easy enough since we still have access to 3, 8, and 9, as well as mathematical operations. We create an array containing the necessary digits and then join with the empty separator "" using the infix :|. Gotchas are (i) the surprisingly low precedence of + and - and (ii) the use of spaces (rather than commas) to separate array elements.

^{In the comments on the cop, @mypronounismonicareinstate suggested 9/9+9/9+9/9+9/9+... as a possible crack. This approach works in theory but not in the online interpreter, which switches over to scientific notation once the sum reaches 1e21.}

  g # Get minimum (useless)

We can remove characters with the o command. For example, kPkPkPL‛∧∑Ėo gives us printable ASCII without a 4, meaning the fourth character of this is now 5. We can remove this and a 4 from another copy of printable ascii, making the fourth character 6. Continuing this, we can get any character in the printable ascii range, but getting the next character costs double (+8) the cost of the previous.

This makes the overhead for C (ord -> char) 171798691832 bytes. The overhead for -, meanwhile, is 11805916207174113034232 bytes.

The evaluated code is going to look something like uu-u-u-u-u-u-u-u-u-u-u-u-u-…, because I'm lazy. We then tack on a C at the end of each, add a W at the end, and sum that with ∑, which we can directly call.

A calculation of the length can be found here. A calculator of the overhead for a single printable ascii calculator can be found here.

Vyxal, 29401143 bytes, lyxal get cracked on

The backbone of this solution is the generation of arbitrary negative numbers, allowing for indexing to get all the commands we need.

---

How negative numbers?

u     # Push -1
 .o   # Remove `0.5` Does nothing except convert to string
   Ė  # Execute

We can decrement to any number by stringing many of these snippets together into a series.

Essentially, this executes subtract, then pushes 1. The 1 is used for the next subtraction in the series. This means we need to get rid of the first subtraction in a series and the last 1 in a series.

Subtraction no

To remove the first subtraction:

k□∑∑k□∑∑

This just pushes a couple of 0s, so the first subtraction is just 0-0.

1 no

To remove the last 1:

uPĖ

This uses -1 to turn 1 into an empty string, which is then executed to remove it.

Why negative numbers tho?

How do arbitrary negative numbers help us? Vyxal uses the same indexing as Python, so we can use negative numbers to index into stuff. However, to index into something, we need i. We don't have that command available to us, but it is in a couple of the builtins, specifically Fizz and aeiou, which we can make use of:

  kv              # Push `aeiou`
    ‛ouo          # Remove `ou`, giving us `aei`
        kfP       # Remove `Fizz`, giving us `ae`
kv         P      # Remove from `aeiou`, giving us `iou`
            ‛ouo  # Remove `ou`, giving us `i`

Now that we have i and any negative number, we can index into our builtins to get useful stuff. For example, we can index into 01234567 to get 1, and we can index into printable ASCII to get + and C. We can use the 1+ over and over to increment a number, then use C to convert it to a character. (Yes, I know I could just push -1 and use - instead of +, which would be a lot shorter, but that's not as fun.)

Once we have the pieces, namely arbitrary negative numbers and indexing, creating a solution becomes trivial. Here's an example for printing !: apparently the link was too long so here's a gist of the program that you can copy into the interpreter.

How?

The first step was to create arbirtrary numbers in some way. I realised that Ė (eval) was overloaded for numbers as reciprocal, and taking the reciprocal of ko (octal digits, 01234567) with koĖĖ gave 8.100005913004317e-07, which had e and -. Both would prove to be useful.

Stripping 01234567 from printable ASCII gave something starting with 89, which I couldn't remove at that point. But I just got 8.100005913004317e-07, which contains both. If I strip that from (ascii - octal digits), and strip that from printable ASCII, I get the digits!

We can get a decimal point from something like 11Ė (1/11, 0.09090909090909091), and stripping both of these from 8.100005913004317e-07 (digits, decimal point, then digits again) gives e-.

Since e is exponentiation, we can just push a 1 before, so the e becomes a NOP, and executing this subtracts a 1, decrementing the top of stack.

We do need a better way to push a 1 though, since we have no whitespace. k1k11ooĖ solves this problem, and is nicely stackable.

So with this, we can get arbitrary negative numbers! Here's a script that generates code for a negative input.

Now, we can get e on its own by stripping -1 from e-:

\$(-2)^{-2}\$ is 1/4, but since we have reciprocal (Ė), we can revert this back to 4. It is as a float, but by stripping 1/11 (0.090909090..., 11Ė) and re-evaling, we can turn this back into an integer:

e's overload for (string, number) is to get every nth character of the string. If we pass in 4, we can get every fourth character of a string. And if we repeat this four times, we can get the first character of any string shorter than 256 chars.

This discovery breaks it all wide open. If we can get the first character of a string, we can remove it, and a new character will become the first character.

Here's a calculator for the size of a character.

Try it Online! Yeah I know there're 4's in there, [DEAL] with it.

The backbone of this solution is our good friend [inf].

We can use [inf] to index into builtins and get some [sweet commands] to execute. To get the [inf], we just exploit some [Classic Vyxal Jankness] with the s command:

       V  # Replace every...
 ₆        #  `64` in...
₆         #  `64` with...
  ₆ĖĖ     #   64.0
     s    #   jankness
      s   #   jankness

Executing the [inf] puts some [unwanted garbage] on the stack, so we remove it by removing it:

₆V  # Remove the [unwanted garbage]

Now that we can index, we can get h from [[Hyperlink Blocked]]. (Yes, this is unnecessary because it's the same as the [inf] indexing we used to get it, but you can shut up you [little slime].)

We can also do things like replace the h in [tHe AlPhAbEt] with [[Hyperlink Blocked]] repeatedly to change the length and [inf] index to get other characters, like o or C:

This code must be stored in a file (-e won't work), but the file name doesn't matter. The source code must be a single line (a shebang line breaks it). A trailing newline in the source code is optional. The `` character in tr:_-z:f-: is DEL (ASCII 127); any character code above 126 would do.

-p gives us automatic printing, which is nice since the core printing functions (print, syswrite, say if we managed to define it) have forbidden names. But it requires input. Fortunately we can change where the input comes from in a BEGIN block: @ARGV specifies where the input comes from, so we set this to the script file, which is guaranteed to exist. We arrange for exactly one line of input, so the code after the BEGIN block runs exactly once and the final value of $_ will be printed at the end.

The rest is simple string processing tricks to set @ARGV and $_ without using any of the forbidden characters. Here's an expanded version with comments.

#!/usr/bin/perl -p
BEGIN {
    # Set @ARGV to $0, a file that we know contains exactly one line.
    # This assumes that perl is invoked on a script file, not with -e.
    $. = ARGU; ++$.;
    $_ = z - z;
    @{$.} = $$_;
}
# For the expanded version only: only process the first line.
print "\n" and exit if $line++;
# Build the string using tr to shift permitted characters into forbidden
# characters. Run tr on $_ since =~ isn't permitted. The . operator is
# permitted so we can concatenate the pieces the simple way.
$_ = BGOP; tr:A-P:!-;:; $z = $_;
# For the digits, arithmetic is more convenient than tr.
$n = $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; ++$.; $n .= $.; $z .= $n;
$_ = $.; tr: -z:#-z:; $z .= $_;
$_ = BLEPRU; tr:A-Z:B-Z:; $z .= $_;
$_ = bdi; tr:G-z:A-z:; $z .= $_;

Try it online! — adapted for modern Perl versions, with the extra m before ?…? that isn't needed in Perl up to 5.21. (To reiterate: the version on TIO does not obey the restricted source constraint, but works in modern Perl. My solution obeys the restricted source constraint, but doesn't work in modern Perl.)

The first thing we do is obtain a string 'a'. We do this by pattern-matching on *_ which is '*main::_'. The characters m and / are forbidden, but ? is permitted, so we can use the m?…? pattern matching form. This form requires an explicit m in modern Perl, but classic Perl allowed a bare ?…? (with the risk that occasionally Perl would misparse the ? as part of the … ? … : … construct). Due to the use of this construct, the program no longer works with Perl 5.22 and above. While we're at it, we grab :: as well; this isn't strictly necessary but saves work later.

Having 'a', we can construct the range 'a'..'_' which is the list of lowercase ASCII letters from 'a' to 'z'. (It should really be 'a'..'z' but perl doesn't mind.) We can now build strings containing letters with $_[INDEX]. Positive integers are expressed as the length of the list (_,_,…,_) in scalar context.

Next we construct the names of some built-in functions from the CORE module. With the function name in $var, we can call it with &$var(…). The . concatenation operator, the chr function (expressed as CORE::chr), and the ability to express integers lets us construct arbitrary strings.

There's no CORE::print, so we use CORE::syswrite(STDOUT, …) instead.

For plain perl the work would be done. For perl -p, we need to do a bit of additional work. perl -p is equivalent to putting the source code in a while (<>) { … } loop. It's so equivalent that you can put an extra } in the source code to close the brace of the loop, followed by an extra { so that the program as a whole is syntactically correct. The structure of the program is:

while (<>) {
    print stuff; $_ = "";
    exit;
    }
    print stuff; $_ = "";
    {
} continue { print $_; }

where the indented part is the source code and the unindented part is the -p wrapper code. So if there is a line of input, the loop body is executed and the program exits. If there is no input, the loop body doesn't run, and the next instructions (the second print stuff;) are executed.

QBasic 1.1, cracks DLosc's second answer

The string to print is:

C,c

Solution:

X$ = MKL$(543370307)
PRINT RTRIM$(X$)

This was much trickier than the first version. This time I couldn't use a comma. That was mainly to prevent writing memory with POKE, but it also ruled out every other function with multiple arguments.

After all my initial ideas failed, I started looking for any functions that took a single argument and were even vaguely related to strings. Eventually I found the MKL$ function, which lets you encode Long values in ASCII. The documentation points out that this "can save up to 6 bytes of storage space" !

MKL$ always returns 4 bytes. If the number isn't long enough, the ASCII encoding will be padded with \0, which QBasic annoyingly prints as whitespace but doesn't trim. I ended up finding a number that gets encoded as C,c with a trailing space, so I could use RTRIM$ to remove that space, all without typing a comma.

Ruby, cracks Dingus's answer

#!/usr/bin/env ruby
class Fixnum
  def !
    chr
  end
end
s = !112 + !46 + !96 + !39 + !92 + !34 + !63 + !37 + !40 + !91 + !58 + !60
eval !112 + !114 + !105 + !110 + !116 + !34 + s + !34

Can't call methods without .? Yes you can, if they're operators.

I have no idea how this works! I found the solution with this generator, then decided against posting it, since that didn't seem to fit the spirit of the challenge. But I decided I'd post it anyway when I saw Dingus's Dupdog answer, which also used generated code.

This should be really really trivial . . . The answer is suspiciously short

PHP 7, 26 bytes, cracks thelmuxkriovar's answer

<?php echo~..............;

Try it online!

This solution contains unprintables so the link is to xxd output which is reversed. Actual bytes are:

<?php echo~\x99\x8a\x91\x8b\x96\x92\xd7\xd6\x84\x82\xa0\xc2\xd0\xa3;

As noted by @thelmuxkriovar this would not work on PHP 8 without quotes.

Try it online! Works in both 5.1 (as required) and 5.3.5 (the version on TIO).

It looks like my crack for the third challenge in the series was unnecessarily convoluted. It's taken me all this time to realise that _G/getfenv() aren't even needed: string itself is a table!

As in the previous challenges, we need to create the string char. We start with chAr and replace the A with a, which is extracted as the third character of _VERSION, a global string that returns Lua 5.1 in 5.1. Once this is done, we simply pass in a list of the required ASCII codes, generated using string[([[find]])] to return the index of the first occurrence of the letter A in strings of the form ccc...A. For reasons I don't understand, the last ASCII code has to be passed to tostring or else the last character gets printed twice.

Hey look, more negative numbers and indexing into printable ascii!

How negative numbers?

kokoĖPĖkokoĖPĖkoĖĖkPkPkPkPkoPkoĖĖPPPPPkokoĖPĖkokoĖPĖkoĖĖkPkPkoPkoĖĖPPPĖkoPPkPkPkPkPkoPkoĖĖPPPPPĖ

We can decrement to any number by stringing many of these snippets together into a series.

This is pretty much the same as emanresu A's way of getting negative numbers, but modified so as not to use 1.

Try it Online!

Why negative numbers tho?

Just like before, we can make use of the negative numbers by indexing into printable ascii. This time, the only builtin that has i in it is printable ascii, but getting the i from there would probably be difficult, and I'm lazy, so I took the easy way out: inf. It turns out, Vyxal is really cursed, so we can do a bit of magic and shenanigans with some floats and casting numbers to iterables and generate a float so absurdly large that it just becomes inf. That can be cast to a string and executed to let us index.

ko           # Push `01234567`
  Ė          # Execute, gives us 1234567
   Ė         # Reciprocal
    Ė        # Reciprocal, gives us 1234567.0
     s       # Sort, gives us inf
      koP    # Strip 01234567, casts to string
         Ė   # Execute
          o  # Remove the extra 0 that was pushed

Now that we have i and any negative number, we can index into our builtins to get useful stuff. For example, we can index into 01234567 to get 1, and we can index into printable ASCII to get + and C. We can use the 1+ over and over to increment a number, then use C to convert it to a character. (Yes, I know I could just push -1 and use - instead of +, which would be a lot shorter, but that's not as fun.)

Once we have the pieces, namely arbitrary negative numbers and indexing, creating a solution becomes trivial.

#@'+1+:00p'<1+1k

The only significant trick user here is self-modifying the , used for output into existence; I generate the characters (and the aforementioned comma) by storing the character one code point lower and adding one to it.

Note that this code does read from the input, and will break if you someone manage to input null bytes, but it performs correctly on no input, and that is allowed. "A pain to implement" was a total understatement.

I will try and golf this and add a better explanation, just wanted to get the crack out there.

Explanation

The basic idea is that in python2 ` can be used to get the string representation of an object. From this we have 3 types of character we get

• numbers. We get numbers by adding booleans to get the desired number and then converting that to its representation. We will also use the number method for indexing.
• '. We get this by getting the representation of False and then the representation of that string. We then take the first character of that.
• \. We get this by taking the representation of True repeatedly until the representation has a backslash to escape a quote, we then index this.

From here we build the string

'\151\155\160\157\162\164\040\163\171\163\073\163\171\163\056\163\164\144\157\165\164\056\167\162\151\164\145\050\047\042\134\047\060\061\062\063\064\065\066\067\070\071\144\164\047\051'

Which is just a pile of octal escape codes for:

import sys;sys.stdout.write('"\'0123456789dt')

Which when run does the proper output.

Being allowed to use () let me use apropos to grab the length-one function names, and then just index them to get the appropriate -/+.
