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.

INPUT "Maximum number: " max%

INPUT "Number of factors: " n%

IF matched% THEN PRINT ELSE PRINT;i%

----------------- FIZZETC (USING RULE SET) ---------------

main :: IO ()

main = mapM_ putStrLn $ take 20 fizzTest

{{Out}}

<pre>1

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:

 

:

b=. * x|/1+i.y

>,&":&.>/(m#inv"_1~-.b),(*/b)#&.>1+i.y

 

Example use:

 

1

2

Fizz

19

 

For our example, b looks like this:

 

1 1 1 1 0 1 1 1 1 0 1 1 1 1 0 1 1 1 1 0

 

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

 

 

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

 

│││Fizz││ │Fizz│ ││Fizz│ ││Fizz││ │Fizz│││Fizz││ │

├┼┼────┼┼────┼────┼────┼┼────┼────┼┼────┼┼────┼────┼┼┼────┼┼────┤

├┼┼────┼┼────┼────┼────┼┼────┼────┼┼────┼┼────┼────┼┼┼────┼┼────┤

│││ ││ │ │Baxx││ │ ││ ││Baxx│ │││ ││ │

 

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

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 <code>fizz(20,[[3,"Fizz"],[5,"Buzz"],[7,"Baxx"]])</code>) or to support exactly factors (keeping the call the same).

Assuming the user specifies as input two facts of the form:

 

A simple Prolog solution to the generalised FizzBuzz problem is as follows:

 

 

loop(B,B,_).

fizzbuzz(N,[(F,S)|Fs],Res) :-

fizzbuzz(N,Fs,OldRes),

 

The program can be launched by querying the predicate

 

It is worth noting that

corresponds to basic FizzBuzz and that the proposed solution can handle an arbitrary number of factors.

Four Two eight...

</pre>

=={{header|R}}==

===... solution===

The task asks that we assume 3 factors for the sake of simplicity. However, R makes the k factors case not much more complicated, so we will do that. The only major downside is that checking for malformed user input becomes so difficult that we will not bother.

{

args <- list(...)

}

genFizzBuzz(105, c(3, "Fizz"), c(5, "Buzz"), c(7, "Baxx"))

 

===Names solution===

If we deviate from the task's example of how to input parameters and instead use R's names facilities to make our (number, name) pairs, we get a much cleaner solution.

{

factors <- sort(namedNums)#Required by the task: We must go from least factor to greatest.

namedGenFizzBuzz(105, namedNums)

shuffledNamedNums <- c(Buzz=5, Prax=9, Fizz=3, Baxx=7)
