Brainfuck - Series of Fibonacci - Slarek - 08-25-2013

Some of you might know Brainfuck, not very efficient coding language but a good brain bender. Anyway, here's an example of Brainfuck, Series of Fibonacci.

How algorithm works:

Code:
m1     m2     m3
a      b      -
a+b    -      b
-      a+b    a+b+b
a+b    -      a+b+b
a+b    a+b+b  -

Code. Remember to remove comments if you use standard compiler.

Code:
+++++      # How many times? Number will be printed: 2n+2.
>+.>+.<<   # m1 = 1, m2 = 1, print them
[->        # while (m0) { m0--, ptr = m1
>[-<+>>+<] # m1 += m2, m3 += m2, m2 = 0
<[->+>+<<] # m2 += m1, m3 += m1, m1 = 0
>[-<+>]    # m1 += m2, m2 = 0
>[-<+>]    # m2 += m3, m3 = 0
<<.>.<     # print m1 ja m2, two consecutive numbers;
<]         # ptr = m0 and the end of the while }

Code without comments:

Code:
+++++>+.>+.<<[->>[-<+>>+<]<[->+>+<<]>[-<+>]>[-<+>]<<.>.<<]

You really should try this, if you want some brain bender. :Smile:

Did you code this? If you did I would love to see a Brainfuck tutorial.

I'm more than happy to make one, thanks for showing intrest :Smile:

Thanks to you to be the one that learned Brainfuck. Please, let me know when you release it.

Actually I will publish it today:Smile:

Here's an implementation of the fibonacci sequence in J;

Code:
f=:(-&2 +&$: <:)^:(1&<)&|**^>:
f i.10+1

Output:

Code:
0 1 1 2 3 5 8 13 21 34 55

I can grab every second fibonacci number for instance as well with very small manipulation:

Code:
fibx=:(-&2 +&$: <:)^:(1&<)&|**^>:
fibx 2 */ (i.10+1)

Code:
0 1 3 8 21 55 144 377 987 2584 6765

I love minimal languages!

Nice. I've never actually programmed in J nor read anything about it.
I shall go and check it

All I see is a series of emoticons lol, for me at least these two languages are very difficult to understand.

Yeah. I haven't checked the J yet but Brainfuck is simple.
But you can't accomplish anything with just a small amount of code

Yeah the code is small but to look at it doesn't make much sense or at least not to me I will read your brainfuck tutorial later on.
