Learning Brainfuck

Designed by Urban Müller in 1993, Brainfuck is a Turing-complete programming language made of eight instructions, each a single character in length, and no operands:

> : increments the data pointer
< : decrements the data pointer
+ : increases byte-value at the data pointer by one
- : decreases byte-value at the data pointer by one
. : converts the byte-value at the data pointer into an ASCII character
, : accepts input an stores it's byte-value at the data pointer
[ : if the byte-value at the data pointer is zero, jump forward to the instruction after the matching ']'
] : if the byte-value at the data pointer is non-zero, jump back to the instruction after the matching '['
