WHAT IS BRAINFUCK?

Brainfuck is a turing-complete, esoteric language that uses only 8 commands.

HOW DO I BRAINFUCK?

mempo = memory pointer

The instructions for writting in brainfuck are the following:

+ --> Adds 1 to the value on the mempo is in.

- --> Removes 1 to the value on the mempo is in.

> --> Changes the mempo by 1.

< --> Changes the mempo by -1.

. --> Outputs ASCII(char) value.

, --> Inputs ASCII(char) value.

[ --> Starts a loop.

] --> Ends a loop if the value of the mempo it's in equals to 0, otherwise it restarts.

Every character other than those is (hopefully) ignored.

ERRORS

If it doesn't work, depending on the return it can be the following:

0   - No problems on the code, check it's well written.

1   - There is an unfinished loop, somewhere.

2   - You are trying to access a negative mempo.

3   - 1 & 2

4   - Not enough input.

5   - 1 & 4

6   - 2 & 4

7   - 1 & 2 & 4
