Overview

Package emulatingstack implements postfix calculator by emulating a stack.

Original is from http://rosettacode.org/wiki/Parsing/RPN_calculator_algorithm#Go where a example of a printed output can be found. This version contains minor changes for this test.

This emulation is not using a stack in the strict sense as the structure is accessed sequentially when only pop/push operations are allowed by definition but it is the most efficient as the "stack" only contains the unused parts of the expression.
