;Task: Write a generalized version of [[FizzBuzz]] that works for any list of factors, along with their words.

This is basically a "fizzbuzz" implementation where the user supplies the parameters.

The user will enter the max number, then they will enter the factors to be calculated along with the corresponding word to be printed.

For simplicity's sake, assume the user will input an integer as the max number and 3 factors, each with a word associated with them.

For example, given:

```
>20      #This is the maximum number, supplied by the user
>3 Fizz  #The user now enters the starting factor (3) and the word they want associated with it (Fizz)
>5 Buzz  #The user now enters the next factor (5) and the word they want associated with it (Buzz)
>7 Baxx  #The user now enters the next factor (7) and the word they want associated with it (Baxx)

```

In other words: For this example, print the numbers '''1''' through '''20''', replacing every multiple of '''3''' with "Fizz", every multiple of '''5''' with "Buzz", and every multiple of '''7''' with "Baxx".

In the case where a number is a multiple of at least two factors, print each of the words associated with those factors in the order of least to greatest factor.

For instance, the number '''15''' is a multiple of both '''3''' and '''5'''; print "FizzBuzz".

If the max number was '''105''' instead of '''20''', you would print "FizzBuzzBaxx" because it's a multiple of '''3''', '''5''', and '''7'''.

## AWK

This is a two-step solution:

• First, we get the parameters, and ** generate a file with the list of numbers (writing directly to that file) ** generate a custom awk-program for that special case (redirecting standard-output)
• the custom program is run, and does the actual work to output the desired result

'''Input:'''

```
105
3 Fizz
5 Buzz
7 Baxx
```

;Usage:

```awk  -f fizzbuzzGenerate.awk  input.txt > fizzbuzzCustom.awk
awk  -f fizzbuzzCustom.awk  numbers.txt
```

;Program:

```# usage:  awk -f fizzbuzzGen.awk > fizzbuzzCustom.awk
#
function Print(s) {
print s > "/dev/stderr"
}

BEGIN { Print( "# FizzBuzz-Generate:" )
q2 = "\""
fN = "numbers.txt"
#fP = "fizzbuzzCustom.awk"
}

NF==1 { Print( "# " \$1 " Numbers:" )
for( i=1; i <= \$1; i++ )
print( i ) > fN   # (!!) write to file not allowed in sandbox at ideone.com

Print( "# Custom program:" )
print "BEGIN {print " q2 "# CustomFizzBuzz:" q2 "} \n"
next
}

NF==2 { Print( "# " \$1 "-->" \$2 )   ##
print "\$1 %  "\$1" == 0 {x = x "q2 \$2 q2 "}"
next
}

END {  print ""
print "!x  {print \$1; next}"
print "    {print " q2 " " q2 ", x; x=" q2 q2 "} \n"

print "END {print " q2 "# Done." q2 "}"
Print( "# Done." )
}
```

## BBC BASIC

This implementation (unlike some of the ones given on this page...) fully obeys the specification, in that it prompts the user for the parameters at run time. It also allows users to specify as many factors as they want, rather than limiting them to three.

```genfizzb
INPUT "Maximum number: " max%
INPUT "Number of factors: " n%
DIM factors%(n% - 1)
DIM words\$(n% - 1)
FOR i% = 0 TO n% - 1
INPUT "> " factor\$
factors%(i%) = VAL(LEFT\$(factor\$, INSTR(factor\$, " ") - 1))
words\$(i%) = MID\$(factor\$, INSTR(factor\$, " ") + 1)
NEXT
FOR i% = 1 TO max%
matched% = FALSE
FOR j% = 0 TO n% - 1
IF i% MOD factors%(j%) = 0 THEN
PRINT words\$(j%);
matched% = TRUE
ENDIF
NEXT
IF matched% THEN PRINT ELSE PRINT;i%
NEXT
```

Output:

```Maximum number: 20

## J

The trick here involves looking for where the factors evenly divide the counting numbers. Where no factor is relevant we use the counting number, an in the remaining cases we use the string which corresponds to the factor:

```genfb=:1 :0
:
b=. * x|/1+i.y
>,&":&.>/(m#inv"_1~-.b),(*/b)#&.>1+i.y
)
```

Example use:

```   3 5 7 ('Fizz';'Buzz';'Baxx')genfb 20
1
2
Fizz
4
Buzz
Fizz
Baxx
8
Fizz
Buzz
11
Fizz
13
Baxx
FizzBuzz
16
17
Fizz
19
Buzz
```

For our example, b looks like this:

```1 1 0 1 1 0 1 1 0 1 1 0 1 1 0 1 1 0 1 1
1 1 1 1 0 1 1 1 1 0 1 1 1 1 0 1 1 1 1 0
1 1 1 1 1 1 0 1 1 1 1 1 1 0 1 1 1 1 1 1
```

`*/b` gives us 1s where we want numbers and 0s where we want to plug in the strings:

```   */*3 5 7|/1+i.20
1 1 0 1 0 0 0 1 0 0 1 0 1 0 0 1 1 0 1 0
```

`m` is our strings, and #inv expands values out to match a selection. So, in our example, `m#inv"_1~-.b` looks like this:

```┌┬┬────┬┬────┬────┬────┬┬────┬────┬┬────┬┬────┬────┬┬┬────┬┬────┐
│││Fizz││    │Fizz│    ││Fizz│    ││Fizz││    │Fizz│││Fizz││    │
├┼┼────┼┼────┼────┼────┼┼────┼────┼┼────┼┼────┼────┼┼┼────┼┼────┤
│││    ││Buzz│    │    ││    │Buzz││    ││    │Buzz│││    ││Buzz│
├┼┼────┼┼────┼────┼────┼┼────┼────┼┼────┼┼────┼────┼┼┼────┼┼────┤
│││    ││    │    │Baxx││    │    ││    ││Baxx│    │││    ││    │
└┴┴────┴┴────┴────┴────┴┴────┴────┴┴────┴┴────┴────┴┴┴────┴┴────┘
```

All that remains is to assemble these pieces into the final result...

## Java

```public class FizzBuzz {

public static void main(String[] args) {
Sound[] sounds = {new Sound(3, "Fizz"), new Sound(5, "Buzz"),  new Sound(7, "Baxx")};
for (int i = 1; i <= 20; i++) {
StringBuilder sb = new StringBuilder();
for (Sound sound : sounds) {
sb.append(sound.generate(i));
}
System.out.println(sb.length() == 0 ? i : sb.toString());
}
}

private static class Sound {
private final int trigger;
private final String onomatopoeia;

public Sound(int trigger, String onomatopoeia) {
this.trigger = trigger;
this.onomatopoeia = onomatopoeia;
}

public String generate(int i) {
return i % trigger == 0 ? onomatopoeia : "";
}

}

}
```

## JavaScript

### ES5

In a functional style of JavaScript, with two nested ''reduce'' folds – one through the integer series, and one through the series of rules.

First as compacted by Google's Closure compiler:

```function fizz(d, e) {
return function b(a) {
return a ? b(a - 1).concat(a) : [];
}(e).reduce(function (b, a) {
return b + (d.reduce(function (b, c) {
return b + (a % c ? "" : c);
}, "") || a.toString()) + "\n";
}, "");
}
```

and then in the original expanded form, for better legibility:

```function fizz(lstRules, lngMax) {

return (
function rng(i) {
return i ? rng(i - 1).concat(i) : []
}
)(lngMax).reduce(
function (strSeries, n) {

// The next member of the series of lines:
// a word string or a number string
return strSeries + (
lstRules.reduce(
function (str, tplNumWord) {
return str + (
n % tplNumWord ? '' : tplNumWord
)
}, ''
) || n.toString()
) + '\n';

}, ''
);
}

fizz([[3, 'Fizz'], [5, 'Buzz'], [7, 'Baxx']], 20);
```

Array.from({ length: max - min }, (_, i) => min + i)

const defaultRules = Object.freeze([

])

// fizzBuzz :: Int -> [[Int, String]] -> String
const fizzBuzz = (max, rules = defaultRules) =>
range(1, max + 1).map(n =>
rules.reduce((words, [factor, word]) =>

) || n

## PARI/GP

{{works with|PARI/GP|2.8.0+}} This version uses a variadic argument to allow more or less than 3 factors. It could be easily modified for earlier versions, either by taking a vector rather than bare arguments (making the call `fizz(20,[[3,"Fizz"],[5,"Buzz"],[7,"Baxx"]])`) or to support exactly factors (keeping the call the same).

```fizz(n,v[..])=
{
v=vecsort(v,1);
for(k=1,n,
my(t);
for(i=1,#v,
if(k%v[i]==0,

## Tcl

Tcl excels at metaprogramming, so this task is trivial. For fun, the below implementation is a compatible extension of [[FizzBuzz#Tcl]]:

```proc fizzbuzz {n args} {
if {\$args eq ""} {
set args {{3 Fizz} {5 Buzz}}
}
while {[incr i] <= \$n} {
set out ""
foreach rule \$args {
lassign \$rule m echo
if {\$i % \$m == 0} {append out \$echo}
}
if {\$out eq ""} {set out \$i}
puts \$out
}
}
fizzbuzz 20 {3 Fizz} {5 Buzz} {7 Baxx}
```

## Ursa

This program reads a max number, then reads factors until the user enters a blank line.

```#
# general fizzbuzz
#
decl int<> factors
decl string<> words
decl int max

# get the max number
out ">" console
set max (in int console)

# get the factors
decl string input
set input " "
while (not (= input ""))
out ">" console
set input (in string console)
if (not (= input ""))
append (int (split input " ")<0>) factors
append (split input " ")<1> words
end if
end while

# output all the numbers
decl int i
for (set i 1) (< i (+ max 1)) (inc i)
decl boolean foundfactor
set foundfactor false
for (decl int j) (< j (size factors)) (inc j)
if (= (mod i factors<j>) 0)
set foundfactor true
out words<j> console
end if
end for
set j 0

out i console
end if
out endl console
end for
```
