The Daily WTF: Curious Perversions in Information Technology

The cornify was really easy to find. But I find myself incapable of understanding WTF the "source code" is supposed to mean.

VinDuv · 2014-09-02 Reply Admin

I think the candidate was trying to find a repeating sequence in the FizzBuzz output, somehow. But your guess is as good as mine…

Same here - what he is trying to achieve with `(1 - 100) / 3` is a complete mystery to me.

But one thing is sure: he hasn't yet come across the modulo operator.

As for the interface / abstract thing: I'm not sure if all languages know the concept of "abstract" so mybe he can be excused there.

aliceif · 2014-09-02 Reply Admin

You don't even need modulo in C++.

int modulo(int n, int m){
   return n - (m * (n / m));
}

Failing a FizzBuzz isn't rare. Failing a FizzBuzz this hard, is.

int modulo(int n, int m){

I need to get back into programming C++...

Hm. Perhaps that function was what he was trying to build in his code snippet?

Edit: fixed broken quoting.

Zacrath · 2014-09-02 Reply Admin

I can't read any of the writing. But I probably wouldn't understand it anyway.

Lawrence · 2014-09-02 Reply Admin

Instead of dividing and remultiplying, C has a standard reference function called "div". It's perfect for people who are annoyed at the idea of needlessly doing an expensive division twice :

#include<stdlib.h>
int modulo(int n, int d) {
    div_t result = div(n, d) ;
    return result.rem ;
}

Of course, if he doesn't know % he won't know about standard C functions. In fact, I'm wondering what this guy actually does know.

You don't need modulo in any language. You don't even need stinking multiplication, division and subtraction in any language. Just good old ++ and a comparison or two will set you straight.

You don't even need ++.

This also is a valid approach at FizzBuzz:

if (i == 0) { cout << 'FizzBuzz\n'; }
else if (i == 1) { cout << i; }
else if (i == 2) { cout << i; }
else if (i == 3) { cout << 'Fizz'; }
else if (i == 4) { cout << i; }
else if (i == 5) { cout << 'Buzz'; }
...

You get my meaning. But would you hire somebody that presented that solution?

The programmer moved to India and became a project manager.

cartman82 · 2014-09-02 Reply Admin

If they wrote a script to output that program, then maybe. Just for curiosity's sake.

aliceif · 2014-09-02 Reply Admin

Even better: A program that creates that program, compiles it, and runs it.

TGV · 2014-09-02 Reply Admin

I was just joking. Why stop at replacing modulo? Perhaps even better: write an enterprise framework, with separate servers for fizz and buzz, which of course have to be synchronized in some devious way. Ah, the possibilities.

The article code looks a lot easier to figure out.

2014-09-02 Reply Admin

We don't need no steenking modulo operator.

int i, f, b; for (i=1, f=1, b=1; i<=100; i++, f++, b++) { ; if (f==3) f=0; ; if (b==5) b=0; ; if (!(f+b)) printf("fizzbuzz\n"); ; else if (!f) printf("fizz\n"); ; else if (!b) printf("buzz\n"); ; else printf("%d\n", i); }

The RWTF is that his code would stop at 100

And recursion. (or stinking goto).

But you need integer division instead. Well, actually any sane IDIV implementation can generate the remainder at the same time for the same effort; it's just usually thrown away by language implementations.

Should this be categorized as Code SOD or Tales From the Interview? I struggle to call that "code" in the usual sense of the word.

The guy thought it was code on some level.

This is special however, on so many levels.

zenmumbler · 2014-09-02 Reply Admin

This candidate should write code for feature films instead. It looks awesome and science-y on paper and makes no sense whatsoever; perfect for Hollywood.

It sorta sits at the intersection of both.

Nah, you can implement it all using nothing more than ++. It won't be pretty though.

Tawnos · 2014-09-02 Reply Admin

No, but if they knew about loop unrolling and mentioned or implemented it as a solution to not require modulo, I'd consider them. Then I'd change the question so they no longer knew the numbers to fizz and buzz on (they would become parameters), requiring them to show modulo or equivalent-logic arithmetic.

dkf · 2014-09-02 Reply Admin

You need an equality test too.

Extra points if the program can output a copy of itself in your choice of language.

darkmatter · 2014-09-02 Reply Admin

How π came into it, I'll never know. But his last part about cout>>8.14 was just him adding Fizz and Buzz, which he appeared to have determined to equal 5 and 3.14 respectively, and printing them out as requested.

Maybe I should have myself committed for managing to possibly understand the method behind that madness.

cellocgw · 2014-09-02 Reply Admin

Hey, counting to 100 should be enough for anybody.

Surly you can build an equality test from an 'is zero' operator.

Wow, I was going to post my Scheme version, but that BrainF**k version beats that all hollow. Oh, well, I'll post it anyway:

#!r6rs
(import
 (rnrs base (6))
 (rnrs lists (6))
 (rnrs io simple (6))
 (rnrs r5rs (6)))

(define (range a b)
   (let count ((x a))
     (if (>= x b)
         (list b)
         (append (list x) (count (+ 1 x))))))

(define (fizzbuzz n)
  (let ((count-list (range 1 n)))
    (map 
     (lambda (fb count)
       (if (string=? fb "")
           count
           fb))
     (map
      (lambda (f b)
        (string-append f b))    
      (map
       (lambda (x)
         (if (= 0 (modulo x 3))
             "Fizz"
             ""))
       count-list)
      (map
       (lambda (x)
         (if (= 0 (modulo x 5))
             "Buzz"
             ""))
       count-list))
     count-list)))

(display (fizzbuzz 100))

EDIT: removed a little bit of redundancy. HTH. DOUBLE EDIT: I forgot the requirement to print the numbers which don't match the pattern. Fixed.

Here's my fizzbuzz contribution:

import re
program = """
if   1 % 15.0 == 0.0: print "fizzbuzz"
elif 1 %  3.0 == 0.0: print "fizz"
elif 1 %  5.0 == 0.0: print "buzz"
else: print 1 

if 1 != 100:
    program = re.sub(" 1 ", " {} ".format( 1 +1), program)
    exec program
"""
exec program

wait... since when could you use the number 1 as a variable in python?

Don't need modulo, just a couple of countdowns... here's an implementation in NetLogo.

to fizzbuzz [ max-fizzbuzz ]
   let fizz 0
   let buzz 0
   let count 0
   repeat max-fizzbuzz
   [ set count count + 1
     set fizz fizz + 1
     set buzz buzz + 1
     ifelse fizz = 3   [ type "fizz" set fizz 0 ] [
     ifelse buzz = 5 [ type "buzz" set buzz 0 ] [
                             type count
     ]]
     print ""
   ]
end

EvanED · 2014-09-02 Reply Admin

You can't. Not really. That's why I like that solution so much, because you get to say things like "if 1 != 100" and it will eventually be false. :-)
