Best brainfuck interpreter I could do in 140 characters, super bad code. You need to change the Q variable to your code for it to run. There are no loops or an input, but the output works just fine.

u/BuRRak

The Q variable declaration is there just so you know what to edit, it could be left out as it is not used anywhere in the code again
u/BuRRak

The output also throws a 0 before every other output

Less random, more structure (perhaps?) :)
