Printing ascending ASCII, Cops

Question

This is the cops' thread. The robbers' thread goes here.

Write a program or function consisting only of printable ASCII characters (that excludes tab and newline) that outputs at least 5 printable ASCII characters in ascending order (from space to tilde / 32 to 126). Characters can be outputted several times, as long as they are adjacent to each other. A single trailing newline is accepted. You must provide the full output, and for every 6 characters in your code you must provide one character in your code, at the position it appears. If your code has 5 or less characters, then you have to reveal only the length. You shall not reveal more than 1 character per 6 in your code.

So if your code alphaprinter outputs the alphabet from a-z, then you need to reveal 2 characters of your code (use underscore for the others), for instance:

al__________  // or
__p__p______  // or
__________er

Rules / specifications:

• You cannot append trailing white spaces that doesn't have a function.
• You can not use comments (but the robbers can use comments when cracking the code)
• Built-in cryptographic primitives (includes any rng, encryption, decryption, and hash) aren't allowed.
• In languages where the default output are like in MATLAB: ans =, then that's accepted, as long as it's clearly stated and shown that ans = is outputted. It should also be clearly stated whether this is part of the "ascending output" or not.
• The output must be deterministic
• Using a non-free language is not accepted
• The output doesn't have to be consecutive characters. Both abcde and abcdg are valid outputs.
• The characters do not need to be distinct as long as the output contains at least 5 characters. aaaaa and aaacc are valid.
• Answers that assumes a REPL environment are not considered to be valid programs or functions and are therefore not allowed.
• STDERR is not considered valid output, but data may written to STDERR.

If the revealed characters are underscores, then you must identify it as shown below. In this case, the second and sixth character are revealed underscores, while the others are unknown.

Note: The robbers only need to find a code that produces the same output. The language, the length of the robbers solution, and the position of the revealed characters must also match.

Your score is the number of characters in your code. The winner will be the submission with the lowest score that hasn't been cracked in 7 days. Only submissions that are posted in 2015 (UTC) are eligible for the win. Submissions that are posted later than this are welcome, but can not win.

In order to claim the win you need to reveal the full code (after 7 days).

Your post should be formatted like this (nn is the number of characters):

---

Language, nn characters

Output:

abcdefghijklmnopqrstuvwxyz

Code (12 characters):

al__________

If the code is cracked, insert [Cracked](link to cracker) in the header. If the submission is safe, insert "Safe" in the header and reveal the full code in your answer. Only answers that have revealed the full code will be eligible for the win.

Answer 1

Python 2, 62 chars, Cracked by Adnan

______________________________________________________________
         | |   ||                  |  |  ||

It kinda looks like a table.

This outputs the string abcde.

Adnan's code:

print "ab_c_de___".replace("_","")#___________________________

My code:

f=lamda _,__,___:"abcde"+'f'*sum(_,__,___)*000;print f(1,2,3);

Answer 2

^{Because I majorly f'ed up my last answer.}

Mouse-2002, 23 chars, safe

Code:

________9<^___________

Output:

!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`ab

Answer 3

Ruby, 32 characters, safe

Output (with no trailing newline):

!"#$%&'(+,./567;<HKLUVWnouvw

Obfuscated code:

________{|c|___________________}

Revealed code:

95.times{|c|c&5*c<7&&putc(c+33)}

Explanation:

Actually pretty straight-forward, just too arbitrary to easily guess or brute-force. For each number c from 0 to 94, bitwise-and c and 5*c. If the result is less than 7, add 33 and output as an ASCII character.

Answer 4

Pyth, 15 characters (safe)

Code:

_CM____________

Output:

"$%'()+-./013456789:;=?BCEFGIKLOPRSTUWXYZ[]^`abcdefghjklmoqsuvxy{|

You can try Pyth online.

I wonder if you can find out the criteria for the characters. :3

Additional hint:

One could have a computers firm like Captor's Fermium totally messed up on just this one puzzle, and still they wouldn't fully solve it. Even the actor Frump Mise couldn't solve it.

Original code

sCMf%sPT3rCN127

Explanation:

rCN127 generates all numbers from 34 (CN = ord('"')) to 127. f%sPT3 finds all the ones that satisfy the following: the sum of the prime factors of n is not divisible by 3. s concatenates the results. The first hint has the number 3, and it refers to filtering the characters/numbers. The additional hint contains 3 anagrams of prime factor sum.

Answer 5

Octave, 22 characters, Safe

Code:

__A____________A___V__

Output:

ans = ABCDFGHHIJLMNNOPRSTTUV

ans = is not part of the output. The output starts with an A.

Real code:

[(A=66:86)+sin(A),'V']

Explanation:

In Octave, variable assignments can be done in the same line they are used. So, the variable A is created starting from 66 (corresponds to A in ASCII) to 86 (corresponds to V in ASCII). +sin(A) creates a small sine wave noise. 'V converts the vector to chars and adds a V at the end. The variable name A and the last letter V was of course chosen to throw people of track =)

This one was made for the robbers. Hope it's neither too hard nor too easy. Good luck :-)

Answer 6

MirBSD Korn Shell, 57 characters, safe

Output:

Revealed code:

local -i1 x=32;while((++x<127));do s+=${x:2};done;echo $s

Answer 7

Recall, 64 characters

Output:

ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~

Code:

_D_0__0_M__________0__0___0_________Z___0____0_____________M____

Pretty straightforward in theory. I made a sandbox here, so you can try things. Keep in mind that infinite loops or deep recursion will crash your tab/browser, so keep a copy elsewhere when trying. You can also download recall.min.js from the link in the title and run it with node.js.

Answer 8

Answer 10

05AB1E, 7 characters, cracked by quintopia

Obfuscated code:

___T___

Original code:

576T*uH

576      # Pushes 576
   T     # Pushes 10
    *    # Multiply the last two items of the stack
     u   # To uppercase, this just returns 576 in string format
      H  # Convert from hexadecimal to decimal

Note: I used the uppercase command to convert the int to a string. This however is a bug and has already been fixed.

Output:

Answer 13

PHP, 68 characters, safe

As usual, don't expect anything short from PHP:

______________________________1_________________________________[1_;
 |    |    |           |               |           |    |      |

Outputs this 252 character long string:

Hint 1

Sometimes you have to "translate" things.

Hint 2

Luckily PHP stores all those helpful "translations" for you internally.

Revealed code

There aren't too many built in functions, that return long strings or arrays with predefined values. One exception is get_html_translation_table. I sorted this array and returned the first character after the & from all escape sequences, e.g. the A from Ä. It has a nice distribution which looks random because the amount of entities related to a letter varies a lot.

$_=get_html_translation_table(1);sort($_);foreach($_ as$_)echo$_[1];

Answer 15

Seriously, 7 characters, (uncracked and noncompeting)

I was inspired by trying to find an answer to Adnan's latest cop, by how close this number was to their number:

___P___

Output:

22366

22366 is the 211th triangular number. The original program was 8PτPurΣ but it is disqualified for containing two non-ASCII characters. It simply takes the 8th prime (23), doubles it (46), finds the 46th prime (211), then pushes the 0-211 range (ur) and sums it.

Purple, 31 characters (safe)

__A_____________o______b__1___b

Full program:

a1AbA1iib{bi1b1Bo1aaa1bbab1Bi1b

Output:

abcdefghijklmnopqrstuvwxyz

Explanation:

It's about the shortest way to print the alphabet in Purple.

1.  a1A    Set to 1-"a" == -96
2.  bA1    Set b to -1 (using the fact that a is always negative)
3.  iib{   Set i=i-b, i.e. i+1. This skips over the "{"
4.  bi1    Set b = i-1 (the cell before the current command, containing "{")
5.  b1B    Set b = 1-"{" == -122
6.  o1a    Output 1-a (which will be the current character)
7.  aa1    Subtract 1 from a (i.e. move to the next character)
8.  bba    Set b=b-a. It will be negative until a==-122, when it will be zero
9.  b1B    Set b=1-what b points to. It will be 0 until a==-122, when it will be -96.
10. i1b    Jump to 1-b. This goes to line 2 until a==-122, when it jumps outside 
           the program and halts.

Answer

Sorry for irrationally difficult problem.

DO#3<-#9DO,1<-#3DO,1SUB#3<-#3~#3DO,1SUB'#3~#3'<-#3~#3DO,1SUB#5<-#338DO,1SUB"&'#3~#3'"<-#27DO,1SUB#4<-#27DO#4<-#28DO,1SUB'#4~#4'<-#4DO,1SUB#6<-"V'#V4'"DO,1SUB#8<-'V"V'#V4'"'DO,1SUB#2<-#333DOREADOUT,1

How it works

DO#3<-#9 changes meaning of the constant.

DO,1<-#3 lets array to have nine item; note previous statement.

DO,1SUB#3<-#3~#3 is equivalent to DO,1SUB#9<-#9~#9, which is equivalent to DO,1SUB#9<-#3.

DO,1SUB'#3~#3'<-#3~#3 does ,1SUB#3<-#3.

DO,1SUB#5<-#338 is equal to DO,1SUB#5<-#18 when READing OUT; this is how Baudot character set works; it cares for only lower five octets.

DO,1SUB"&'#3~#3'"<-#27 does ,1SUB#1<-#27.

DO,1SUB#4<-#27 is obvious, as none of those constants are not overloaded yet.

DO#4<-#28 now overloads the operand.

DO,1SUB'#4~#4'<-#4 now does ,1SUB#7<-#28.

DO,1SUB#6<-"V'#V4'" is actually DO,1SUB#6<-#30.

DO,1SUB#8<-'V"V'#V4'"' does ,1SUB#8<-#31

DO,1SUB#2<-#333 does what it says.

Finally, output is done by DOREADOUT,1.

By the way the reason why an array requires 9 items to output 5 characters is: tail arrays adopt extended Baudot character set. The character set has a concept of "state": uppercase, lowercase, figures, and symbols. When a same value is READ OUT with different state, the different character is READ OUT
