fizzbuzz

C#の研修を見学中にifとfor使わずに書こうって言われた
しかしながら自分の端末にcsc入れてなかったのでF#で書いた

let printNumber(count) =
        let isDivided3 = (count % 3 = 0)
        let isDivided5 = (count % 5 = 0)

        match (isDivided3, isDivided5) with
        | (true, true) -> printfn "fizzbuzz"
        | (true, false) -> printfn "fizz"
        | (false, true) -> printfn "buzz"
        | (false, false) -> printfn "%d" count

let rec fizzbuzz(count) = 
    printNumber(count)

    match count with
    | 100 -> ()
    | _  -> fizzbuzz(count + 1)
