BrainHack vs Pebbl

BrainHack is an interpreter app for B*******k. The B*******k programming language is an esoteric programming language noted for its extreme minimalism. It is a Turing tarpit, designed to challenge and amuse programmers, and was not made to be suitable for practical use. It was created in 1993 by Urban Muller. Commands: > increment the data pointer (to point to the next cell to the right). < decrement the data pointer (to point to the next cell to the left). + increment (increase by one) the byte at the data pointer. - decrement (decrease by one) the byte at the data pointer. . output a character, the ASCII value of which being the byte at the data pointer. , accept one byte of input, storing its value in the byte at the data pointer. [ if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. ] if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
