Fun with FizzBuzz

Lazily generate fizzbuzz results and provide a test function. Parameterize the inputs and predicates.

Generate a FizzBuzz result set given two predicates and a max value

 ``` 1: 2: 3: 4: 5: 6: 7: 8: 9: 10: ``` ``````let getFizzBuzz pred1 pred2 (n: int) = match pred1 n, pred2 n with | 0,0 -> "FizzBuzz" | 0,_ -> "Fizz" | _,0 -> "Buzz" | _ -> string n let fizzbuzz pred1 pred2 = let getFizzBuzz = getFizzBuzz pred1 pred2 Seq.unfold(fun n -> Some(getFizzBuzz n, n+1)) 1 ``````

Generate the Coding Horror FizzBuzz

 ``` 1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13: 14: ``` ``````fizzbuzz (fun x -> x%3) (fun x -> x%5) |> Seq.take 100 |> Seq.toArray (* Results: val it : string [] = [|"1"; "2"; "Fizz"; "4"; "Buzz"; "Fizz"; "7"; "8"; "Fizz"; "Buzz"; "11"; "Fizz"; "13"; "14"; "FizzBuzz"; "16"; "17"; "Fizz"; "19"; "Buzz"; "Fizz"; "22"; "23"; "Fizz"; "Buzz"; "26"; "Fizz"; "28"; "29"; "FizzBuzz"; "31"; "32"; "Fizz"; "34"; "Buzz"; "Fizz"; "37"; "38"; "Fizz"; "Buzz"; "41"; "Fizz"; "43"; "44"; "FizzBuzz"; "46"; "47"; "Fizz"; "49"; "Buzz"; "Fizz"; "52"; "53"; "Fizz"; "Buzz"; "56"; "Fizz"; "58"; "59"; "FizzBuzz"; "61"; "62"; "Fizz"; "64"; "Buzz"; "Fizz"; "67"; "68"; "Fizz"; "Buzz"; "71"; "Fizz"; "73"; "74"; "FizzBuzz"; "76"; "77"; "Fizz"; "79"; "Buzz"; "Fizz"; "82"; "83"; "Fizz"; "Buzz"; "86"; "Fizz"; "88"; "89"; "FizzBuzz"; "91"; "92"; "Fizz"; "94"; "Buzz"; "Fizz"; "97"; "98"; "Fizz"; "Buzz"|] *) ``````
