This contest is officially over, the winner is jimmy23013. Congratulations!

The challenge is to make a program that prints Hello World! to stdout. The catch is that your program must have a Levenshtein distance of 7 or less from the program in the answer submitted before yours.

How This Will Work

Below I have already submitted the first answer using Python: print("Hello World!").

The next person to answer must modify the string print("Hello World!") with up to 7 single character insertions, deletions, or substitutions so that when it is run in any language that hasn't been used so far (only Python in this case) the output is still Hello World!.

For example the second answerer might use 1 substitution (r -> u), 2 deletions (in), and 1 insertion (s) to make the string puts("Hello World!") which prints Hello World! when run in Ruby.

The third person to answer must do the same thing in a new language, but using the program of the second person's answer (e.g. puts("Hello World!")) as their starting point. The fourth answer will be in relation to the third answer and so on.

This will continue on until everyone get stuck because there is no new language the last answer's program can be made to run in by only changing 7 characters. The communal goal is to see how long we can keep this up, so try not to make any obscure or unwarranted character edits (this is not a requirement however).

Formatting

Please format your post like this:

# Answer N - [language]

    [code]

[notes, explanation, observations, whatever]

Where N is the answer number (increases incrementally, N = 1, 2, 3,...).

You do not have to tell which exact characters were changed. Just make sure the Levenshtein distance is from 0 to 7.

Rules

The key thing to understand about this challenge is that only one person can answer at a time and each answer depends on the one before it.

There should never be two answers with the same N. If two people happen to simultaneously answer for some N, the one who answered later (even if it's a few seconds difference) should graciously delete their answer.

Furthermore...

  • A user may only submit one answer per 8 hour period. i.e. Each of your answers must be at least 8 hours apart. (This is to prevent users from constantly watching the question and answering as much as possible.)
  • A user may not submit two answers in a row. (e.g. since I submitted answer 1 I can't do answer 2, but I could do 3.)
  • Each answer must be in a different programming language.
    • Different versions of the same language count as the same language.
    • Languages count as distinct if they are traditionally called by two different names. (There may be some ambiguities here but don't let that ruin the contest.)
  • You may only use tabs, newlines, and printable ASCII. (Newlines count as one character.)
  • The output should only be Hello World! and no other characters (a leading/trailing newline is not an issue).
  • If your language doesn't has stdout use whatever is commonly used for quickly outputting text (e.g. console.log or alert in JavaScript).

Please make sure your answer is valid. We don't want to realize there's a break in the chain five answers up. Invalid answers should be fixed quickly or deleted before there are additional answers.

Don't edit answers unless absolutely necessary.

Scoring

Once things settle down, the user who submits the most (valid) answers wins. Ties go to the user with the most cumulative up-votes.

Answer 173 - Vitsy

Distance 7 from answer 172

4mrZ"#03w(*#class jux!{public static void main(String[] h){#\
#System.Console.Writeln(//@\//Hello*}}print,cat<<#*)\
put"
a
"Hello World!";#(O).g!)S(#X` ;}}//printputsx;//-##E;]bye</>#*)

Oh, geez, that was easier than I expected it to be.

Explanation:

4mrZ inserted (4 chars), which calls the 4th index of code (the 5th line), reverses the stack, and then outputs everything in the stack as a char. I can get away with no newline due to the # character, which will teleport to the 90th character in the first line (which doesn't exist) (Z in ASCII), throwing an error and exiting the program.

Newline inserted before "Hello... (one char) to designate a new method line.

" substituted for ' at the end of World!' (one char) to end the quotes.

; inserted after the newly substituted " (one char), which is a return character. This leaves Hello, World! on the stack.

More interestingly, if you want to know what Vitsy is actually reading, here's the verbose mode version (any lines starting with : designate a newline):

Distance 4 from Answer 179. Try it online!

Explanation

The program starts with an if statement. Since the stack is empty, that makes all of i#^.`4mrZ"#03w(*#class jux!{public static void main(String[ no-ops. When it gets to ], it closes all if statements, loops, etc. But, right ahead of that is another if. Once again the stack is still empty, so all of

ih){#\
#System.Console.Writeln(//@\//Hello*}

is a huge no-op. Next, p checks if top of stack is prime. Yet again the stack is empty, so it's also a no-op. Same goes with r; it just reverses the (empty) stack. Then the program encounters i with an empty stack again, so

int,cat<<#*)\
#put"

#^
is~ob

is yet another no-op. Again, the ] exits all if statements, loops, etc. Next 05AB1E parses "Hello World!" as a literal string and pushes it to the stack. Finally, q exits the program, making the rest of the code a no-op, and implicitly outputs top of stack.

Answer 55 - Pixie; fallback option: ClojureCLR

"//echo o[.>]c;cat<<;#&&alert"(printf
"Hello World!")

Distance 3 from answer 54

The language is in early alpha and seem to have only REPL. Example session:

$ ./pixie-vm 
Pixie 0.1 - Interactive REPL
(linux, gcc)
----------------------------
user => "//echo o[.>]c;cat<<;#&&alert"(printf
//echo o[.>]c;cat<<;#&&alert
user => "Hello World!")
12
Hello World!user => 
$ 

When run outside REPL, I expect it to output just "Hello World!", without additional things.

The language is inspired by Clojure. The script works in Clojure too (without messy additional REPL output)

Here is example of ClojureCLR session (used clojure-clr-1.3.0-Debug-3.5.zip):

$ mono Clojure.Main.exe hello.clj ; echo
Hello World!
$

Answer 111 - TPP

--##[][.]#i--#main(){puts(select"
Hello World!
--##[;]#bye;dnl</>%

Distance 7 from Answer 110: moved select " to the line above and removed the space (2 deletion2), changed --# to --## on both lines (2), removed the "; from the end of the second line (2), and changed the space between select and " to a newline (1). As my sed post was deleted, I am assuming that I can post without waiting 8 more hours. This doesn't print "Hello World!", but displays it instead. If this is an unsatisfactory answer, let me know.

  • \$\begingroup\$ Moving select " from the second line to the first line takes 2, and removing the space takes 1. You're counting only 2 (your first step and your fourth step). \$\endgroup\$

    \$\begingroup\$ It helps if people explain their answers some. Without research, one can't tell if this outputs leading or trailing spaces. The problem statement says: "The output should only be Hello World! and no other characters (a leading/trailing newline is not an issue)." so if there is (for instance) a rule by which leading and trailing spaces are stripped somehow that would be nice to point out the nuances of. Or whatever mad science is happening to meet the requirements; if " Hello World! " isn't a string constant but the quotes mean something else, etc. \$\endgroup\$ Oct 30, 2014 at 19:36
  • \$\begingroup\$ The wiki page says like Forth, quotes must be space separated so I think the lines with out the space separation are ignored and the Hello World! line prints correctly. Now mine finally fits I login and I can't answer cos it's protected! Noooooooooooooooo \$\endgroup\$

Answer 115 - RegXy

a/-##[][/]#i--#main(){pu/s(
sel/.*/Hello World!/ 
b/"-##[;]#bye;nl</>%"

Distance from Answer 114 : 7

RegXy is based on Regular Expressions, perl styled.

label/regex/target_label means if the regex matches, go to the target_label line

label/regex/replacement/ means replace the regex match with replacement text.
