Coffee → Code

Hacktoberfest again! It’s time to help the world became a better place by contributing opensource repos. This year I’ll start with a fun little puzzle from @narze that ask to change Coffee into Code. Which should be super duper (too) easy 😂

Well, let’s make it fun also. Ditch the mainstream daily life language (those Python, C++) and just follow the early Google Code Jam philosophy that’s allow esoteric language. So, let’s Brainfuck again! (though I’ve use it just once lol)

PART 1 INIT THE WORD COFFEE
===========================
++++ ++++ ++++ ++++     work with hexadecimal
[                       this loop will init 6 chars closest to coffee
  > ++++                add 2 plus in this line to lower 1st char
  > ++++ +++            or delete 2 plus onward to upper all chars
  > ++++ ++
  > ++++ ++
  > ++++ ++
  > ++++ ++
<<<< << - ]             condition to exit the dowhile loop
> +++                   adjust @ to c
> -                     adjust p to o
> ++++ ++               you
> ++++ ++               get
> ++++ +                the
> ++++ +                idea
[<]                     reset head
>[.>]<[<]               print the initial word / this line can be omitted


PART 2 CONVERT COFFEE TO CODE
=============================
>                       skip the c
>                       skip the o
> --                    change 1st f to d
> [-]                   remove 2nd f
> [-]                   remove 1st e
> [-<<+>>]              move 2nd e to the back of previous d
<<[<]                   reset head
>[.>]<[<]               print the final word after conversion

Inspecting it worth a million words. So go try it at fatiheriki.github.io/brainfuck-visualizer.
