BFStack

BFStack is an esoteric brainfuck derivative. It is stack based instead. The instructions are almost the same, but changed to be stack based.

Instructions

• > pushes 0 onto the stack
• < pops the top of the stack
• . prints top of stack as ASCII
• , pushes ASCII input to top of stack
• + increments the top of the stack
• - decrements the top of the stack
• [ jumps to the corresponding ] if the top of the stack is 0
• ] jumps to corresponding [ if the top of the stack isn't 0

Computational class

This is a Push-down automaton, as it would be equivalent to brainfuck, except for it cannot access the non top-of-stack cells.
