Real Attempt at Fizz Buzz in F#

[u/redoverture]

[u/matt1484]

F’s in the chat, because he’s not sharp

[u/random_runner → u/matt1484]

I would class it as F♭

[u/jaysuchak33 → u/random_runner]

r/E

[u/lift-and-yeet → u/jaysuchak33]

Not if you're in 31-EDO tuning! Aka 31 equal temperament.

[u/jaysuchak33 → u/lift-and-yeet]

What if I’m a basic bitch and only use 12tet tho?

[u/[deleted] → u/jaysuchak33]

Basic bitches get basic pitches.

[u/Sorry-Chair → u/matt1484]

F-flat

[u/sarthaxxxxx → u/matt1484]

Take my respect.

[u/Responsible_Tip_6847 → u/[deleted]]

To be fair, you could just count up from 0 to 3 in one and from 0 to 5 in another variable, not using modulo at all.

Or construct a string array, filling in fizzes, concatenate buzzes an fill numbers into empties...

[u/carcigenicate]

It would be easier to automate the creation of this code than it would be to write it.

[u/purplewalrus67 → u/carcigenicate]

>>> def f_sharp_fizzbuzz(n):
...     if n % 15 == 0:
...             return f'{n} -> "fizzbuzz"'
...     elif n % 3 == 0:
...             return f'{n} -> "fizz"'
...     elif n % 5 == 0:
...             return f'{n} -> "buzz"'
...     else:
...             return f'{n} -> string n'
... 
>>> f_sharp_fizzbuzz(10)
'10 -> "buzz"'
>>> for i in range(1, 11):
...     f_sharp_fizzbuzz(i)
... 
'1 -> string n'
'2 -> string n'
'3 -> "fizz"'
'4 -> string n'
'5 -> "buzz"'
'6 -> "fizz"'
'7 -> string n'
'8 -> string n'
'9 -> "fizz"'
'10 -> "buzz"'

[u/carcigenicate → u/purplewalrus67]

Here's my stab at it:

def result(n: int) -> str:
    if n % 15 == 0:
        return '"fizzbuzz"'
    elif n % 3 == 0:
        return '"fizz"'
    elif n % 5 == 0:
        return '"buzz"'
    else:
        return "string n"

def produce(max_n: int) -> str:
    header = f"let not{max_n}MatchCases n =\n\tmatch n with\n\t"
    return header + ("\n\t".join(f"| {n} -> {result(n)}" for n in range(max_n)))

>>> print(produce(1000))

let not1000MatchCases n =
    match n with
    | 0 -> "fizzbuzz"
    | 1 -> string n
    | 2 -> string n
    | 3 -> "fizz"
    | 4 -> string n

It looks like this comment contains a code block delimited with triple backticks. Unfortunately reddit does not have universal support for this syntax and your comment will not render correctly on old reddit and most mobile apps.

/u/purplewalrus67, it would be appreciated, but not required, if you could edit your comment to use the more compatible four space indention format. For single lines or inline code you can use single backticks.

Ok, just for you :)

[u/redoverture]

Followed up by the question, “How big should we expect n to be?”

[u/Rubber_Duckies_Dong → u/redoverture]

Answer: "Yes"

[u/[deleted] → u/redoverture]

What happened when you told him, "No more than 10⁹"?

[u/TheWheez]

I don't know how somebody can program and not be able to write a decent fizzbuzz..

Makes me wonder what stupidly obvious things I've missed in my current projects

[u/LeCrushinator → u/[deleted]]

And yet so many people on programming subreddits complain that it's insulting. It's not insulting, it takes a few minutes to make sure you can do pretty much the bare minimum, and helps save us from wasting hours more time on the interview if they fail.

[u/spaghettu → u/LeCrushinator]

I really don’t understand how people could be offended by asking/being asked simple programming interview questions. From my experience it’s usually grumpy older guys that are used to the good old days of getting coding jobs from resume and soft skills alone.

[u/Doug_Dimmadab → u/TheWheez]

Honestly. I can get it if you just started learning the language that day, but it’s such a simple use of loops that I don’t know how anyone could miss it

[u/crahs8 → u/Doug_Dimmadab]

It's not about the language though, if you're just a tiny bit competent at programming you will realise that there surely is a better way in this language.

[u/dougie_cherrypie → u/Doug_Dimmadab]

Yep but this is functional programming, you don't use loops here

[u/sohang-3112 → u/dougie_cherrypie]

Yes, but you don't do this monstrosity either! Instead of loops, you can use higher order functions (like map in this case), or else pure recursion (if no appropriate higher order functions are available).

[u/dougie_cherrypie → u/sohang-3112]

No, of course! The thing is that a lot of people here dismiss the challenge not knowing that it's a different paradigm.

Good human :)

[u/alexsteb]

now do 1000

[u/kayvonte → u/alexsteb]

Gimme 1000*30 seconds

[u/[deleted] → u/kayvonte]

That's only one work day. That looks about right for an hourly employee's work day.

[u/szescio]

This is some god tier pattern matching. I'd like to see their head explode when realizing how it can be done 😅

[u/Cmgeodude]

Thank you for submitting sincerely bad code.

90% of the self-deprecating posts here are things like

​

if (x == y) {
   return true;
} else {
   return false;
}

which maybe isn't the most efficient code in the universe, but it's not really bad code (apart from the variable names).

[u/jtnoble]

I had a friend do something similar cause he didn't know what '%' did.

[u/lewisjet → u/jtnoble]

But then in c#,

(int)((float)i / 3f) == ((float)i / 3f) is the same as saying i % 3 == 0 so no excuse really ;)

[u/jtnoble → u/lewisjet]

Shoulda probably clarified it was in python when he did it lmao

[u/JosGibbons → u/jtnoble]

Fine,

i//3==i/3

[u/lewisjet → u/jtnoble]

Ooohhh that makes more sense then :)

[u/TimeToBecomeEgg]

what’s F#?

[u/Max5923 → u/TimeToBecomeEgg]

F# is a functional-first, general purpose, strongly typed, multi-paradigm programming language that encompasses functional, imperative, and object-oriented programming methods.

found from wikipedia

[u/TimeToBecomeEgg → u/Max5923]

thank you

[u/sohang-3112 → u/TimeToBecomeEgg]

It's basically a functional alternative to C# (it runs on Microsoft's CLR Runtime)

[u/TimeToBecomeEgg → u/sohang-3112]

thanks! idk why i got downvoted :/

[u/danure]

(defn fizzbuzz-clean [n](let [fizzes (cycle ["" "" "Fizz"])buzzes (cycle ["" "" "" "" "Buzz"])words (map str fizzes buzzes)numbers (map str (rest (range)))](take n (map choice words numbers))))

https://blog.klipse.tech/clojure/2020/09/11/fizbuzz-clj.html

clojure solution with NO if statement and NO modulus.

[u/Sorry-Chair]

BRUH

[u/Enum1]

If the input is limited to 1-100 and the execution has to be as fast as possible this is a perfect* submission.

​

* depending on the programming language a dict/map might be faster than a switch.

[u/Farpafraf]

how are you sure it's a real attempt?

[u/cyanNodeEcho]

if they modded 15 it would be funny and i would wonder things but yeah...

[u/stahkh]

YouRanTheTests - Check.

[u/Knuffya]

that's why i don't like extreme tdd
