I also might as well do the v3 one while I'm at it, since it's trivial.

function fibonnaciSequence(iterations) { 
    var sequence = 1;
    var prev = 0;
    var current = 1;

    if (iterations == 0) return undefined;

    for (var i = 0; i < iterations; i++) {
        current += prev;
        prev = current - prev;
        sequence += ', ' + current;
    }

    return sequence;
}

Sample output: "1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, 514229, 832040, 1346269"

Will implement better input checking and large number handling next I guess, what language is good for this? I only know C++, Java and Javascript but I don't mind learning something new.

Otherwise I'll probably just do it in C++.

Always wandered - why bootloader is "Fuck you"?

If by "bootloader" it means something like grub that will be able at least boot into linux and windows - then yes, its quite challeneging but "Difficult" at most.

If its just requires to be able to boot from the media at all and just display Hello World or whatever than its just trivial.

What the frick is not constant about i? I mean i did put the const modifier before i right RIGHT?

fuckin meme fibonaci

def fibonnaci(n):
  i=0
  j=1
  for m in range (0,n):
    print j
    tmp = i+j
    i=j
    j= tmp

not even trying

Spinning.

>>57834100
Use a better language next time:

let fibonnaci n =
  let rec loop i j = function
    | m when m = n -> j
    | m -> loop j (i + j) (succ m) in
  loop 0 1 0

Open for interpretation, I assume.

#PIPY
from decimal import *

for x in range(n):

print(sum(pi))

>>57835594
you can skip building the list by using a generator comprehension.

print(sum((1/Decimal(16)**x)*(Decimal(4)/(8*x+1)-Decimal(2)/(8*x+4)-Decimal(1)/(8*x+5)-Decimal(1)/(8*x+6))
          for x in range(n)))

Ok here's my shitty and ARBITRARY love calculator.

#lang typed/racket

(: score (String . -> . Nonnegative-Integer))
(define (score s)
  (foldl + 0 (map char->integer (string->list s))))

(: love (String String . -> . Nonnegative-Exact-Rational))
(define (love a b)
  (/ (abs (- (score a) (score b))) 500))

(module+ main
  (define a (read-line))
  (define b (read-line))
  (if (and (string? a) (string? b))
    (displayln (format "Your love score between ~a and ~a is ~a"
                       a
                       b
                       (love a b)))
