Introduction

In our recent effort to collect catalogues of shortest solutions for standard programming exercises, here is PPCG's first ever vanilla FizzBuzz challenge. If you wish to see other catalogue challenges, there is "Hello World!" and "Is this number a prime?".

Challenge

Write a program that prints the decimal numbers from 1 to 100 inclusive. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

Output

The output will be a list of numbers (and Fizzes, Buzzes and FizzBuzzes) separated by a newline (either \n or \r\n). A trailing newline is acceptable, but a leading newline is not. Apart from your choice of newline, the output should look exactly like this:

1

The only exception to this rule is constant output of your language's interpreter that cannot be suppressed, such as a greeting, ANSI color codes or indentation.

Further Rules

  • This is not about finding the language with the shortest approach for playing FizzBuzz, this is about finding the shortest approach in every language. Therefore, no answer will be marked as accepted.

  • Submissions are scored in bytes in an appropriate preexisting encoding, usually (but not necessarily) UTF-8. Some languages, like Folders, are a bit tricky to score--if in doubt, please ask on Meta.

  • Nothing can be printed to STDERR.

  • Feel free to use a language (or language version) even if it's newer than this challenge. If anyone wants to abuse this by creating a language where the empty program generates FizzBuzz output, then congrats for paving the way for a very boring answer.

    Note that there must be an interpreter so the submission can be tested. It is allowed (and even encouraged) to write this interpreter yourself for a previously unimplemented language.

  • If your language of choice is a trivial variant of another (potentially more popular) language which already has an answer (think BASIC or SQL dialects, Unix shells or trivial Brainfuck derivatives like Alphuck and ???), consider adding a note to the existing answer that the same or a very similar solution is also the shortest in the other language.

  • Because the output is fixed, you may hardcode the output (but this may not be the shortest option).

  • You may use preexisting solutions, as long as you credit the original author of the program.

  • Standard loopholes are otherwise disallowed.

As a side note, please don't downvote boring (but valid) answers in languages where there is not much to golf; these are still useful to this question as it tries to compile a catalogue as complete as possible. However, do primarily upvote answers in languages where the authors actually had to put effort into golfing the code.

    \$\begingroup\$ I’m not sure I like the fact that you hardcoded the 100 into the challenge. That way, a program that just generates the expected output is a valid entry, but is not interesting for this challenge. I think the challenge should expect the program to input the number of items to output. \$\endgroup\$

Explanation

"d"[...].        For loop that loops from 0 to 99, then stops
i1+              Loop counter + 1 (so it's 1 to 100)
d5%6&"Buzz"      Divisibility test by 5, skips "Buzz" if not divisible
0c3%6&"Fizz"     Divisibility test by 3, skips "Fizz" if not divisible
I1-              Length of stack minus 1 (0 if there's no Fizz or Buzz)
3&N6@            Output as integer if ^ is 0, skip character output otherwise
0gx(O)           Dump the loop counter and output "Fizz"/"Buzz"/"FizzBuzz"
25*O             Print newline

There were only 7 XQuery answers on the whole site, I thought it could at least have its FizzBuzz ! Granted it's not very golfy, in particular when you need to add a 36 bytes preface so that it does not output an XML header.

I tested it with Saxon-HE's command-line XQuery tool (java net.sf.saxon.Query fizzbuzz.xq), with which I had to replace the w3-defined option declaration with declare option saxon:output "method=text";.

I will try to explain each section of code:

V!         !<  Add 1 to each number that goes to the left of the a
           1|  and sends it to the bottom of the V
           a|
           -<

(102)          The 102 falls to the left of the e and each number
 e             that passes over is compared to 102.
#H             If a number is equal then the H runs and ends the program

  #r3#         With each number that goes above the r
    #          the remainder of dividing by 3 is obtained.
   N           The N returns 1 if the number is 0, and 0 otherwise.
"Fizz"         The string "Fizz" falls and moves to the left of the m.
               The number is multiplied by the string
   mX          ("" or "Fizz" if it is 0 or 1 respectively)
###            The X removes the number when it moves to the right

               The same is done with 5 and "Buzz"

   mX  mX      
    V-->      Both strings are concatenated with the A
   A          getting "", "Fizz", "Buzz" or "FizzBuzz"
    #

  ' C         The C changes the direction of advance of string, to the left.
  'e          At the same time the "e" compares the string with the empty string.
  #           The single quotes are a vertical literal string.

 V            The V and pipes redirects the string to the right of the C
 |            that changes the direction again in order that comes to the left of the A
 <V
 C  A

          Y   The original number is converted to a string with Y.
          !



          !   Pipes and teleporters (!) Redirects the string to below the V
     V---->

    M         The string falls to the right of the M and multiplies
   # #        with the number previously obtained by the e
    A         The result is above the A

      "\n"   The string "\n" falls on the v which makes a copy
    M  #     whenever there is a space below.
      v      The C changes the direction of the string so it goes to the left.
    A  C     It waits to the right of the A

    A        The A concatenate all 3 strings, the result is on the w that sends it
  #X ##      to the O representing the output. At the same time the X deletes the string.
    w
    O#

I hope it is comprehensible, English is not my main language.

This is a fairly basic (and slightly unimaginative) answer.

Explanation

C pushes 100 to the stack, which means that ...

F is the FizzBuzz builtin. This was mainly added in as a basic stack based program but got left in as a command and I never got rid of it.

Not as long as I expected it to be, maybe because I ommited main function and used an enum. Quite overcomplicated print statement.

Notes:

This ^^ is pretty much a q version of the k solution, so I've written in a different way.. unfortunately it's about 50% slower :(

0{(`Fizz;`Buzz;y)(&)(0=a),all a:mod[y;3 5]}'1+(!)100

Here we are indexing into a list of Fizz, Buzz, based on the result of the modulo operation... The k solution style is better.

(f 1 2 4

Try it online! (Note that the repl auto-completes parentheses at the ends of lines; these have been filled in on the TIO version.)

Explanation

It took me a while to realize I could do FizzBuzz in tinylisp, since the language doesn't have strings. However, it does have the Name type, which can be any run of non-whitespace, non-parenthesis characters; and it also has the disp command, which outputs a value followed by a newline. Together with some creative abuse of recursion, we can get the desired output.

We define a function f with three arguments:

  • n is the counter. We will start at 1 and recurse until 100.
  • # is the number of iterations till the next divisible-by-3 number. (Mnemonic: Shift-3)
  • % is the number of iterations till the next divisible-by-5 number. (Mnemonic: Shift-5)

The first thing f does is check whether n is 100. If so, we return Buzz. This value gets passed all the way up the call stack and printed at the end.

If not, we need to use disp to print either the number, Fizz, Buzz, or FizzBuzz, depending on the values of # and %:

  • If # and % are both nonzero (truthy), the number is not divisible by 3 or 5. Display the number, n.
  • If # is nonzero but % is zero, the number is divisible by 5 but not 3. Display Buzz.
  • If # is zero but % is nonzero, the number is divisible by 3 but not 5. Display Fizz.
  • If # and % are both zero, the number is divisible by 3 and 5. Display FizzBuzz.

Since tinylisp does not have an equivalent to Common Lisp's progn, disp'ing something and then returning a value requires a little trickery. Since disp always returns (), which is falsey, we can use the disp call as the condition of an if (i). The true branch will never be evaluated (0 is a convenient placeholder), and we can put the actual return value in the false branch.

This return value is a recursive call. We add 1 to n, and we subtract 1 from # and % unless they are zero, in which case we reset them to (3-1) or (5-1), respectively.

Ungolfed, using the standard library for long names of builtins (TIO):

(load library)

(def fizz-buzz
 (lambda (counter steps-till-fizz steps-till-buzz)
  (if (equal? counter 100)
   (q Buzz)
   (if
    (disp
     (if steps-till-fizz
      (if steps-till-buzz counter (q Buzz))
      (if steps-till-buzz (q Fizz) (q FizzBuzz))))
    (comment Return val of disp is always falsey, so the true branch is never executed)
    (fizz-buzz
     (add2 counter 1)
     (if steps-till-fizz (sub2 steps-till-fizz 1) 2)
     (if steps-till-buzz (sub2 steps-till-buzz 1) 4))))))

(fizz-buzz 1 2 4)

    \$\begingroup\$ Ken Thompson: "Thompson:the original LISP... you know I think it's a horrible language. I really do. But, I was struck with the idea of defining very, very low level semantics,... it defines its own interpreter. It's always been a problem when you describe a language to say what constructs it recognizes and what they actually do and [Lisp] was the cleanest, simplest, most recursive, beautiful semantics of a language I've ever seen. Probably even to this day. But, unfortunately, what it describes I think is just a horrible language." tinylisp is a bit less scary IMHO! \$\endgroup\$
