Reverse Polish Notation
Definition 1:
Reverse Polish notation (RPN), also known as postfix notation, was invented by Australian philosopher and computer scientist Charles Hamblin in the mid-1950s, to enable zero-address memory stores. It is derived from the Polish notation, which was introduced in 1920 by the Polish mathematician Jan Lukasiewicz....
In RPN the operands precede the operator, thus dispensing with the need for parentheses... Implementations of RPN are stack-based; that is, operands are popped from a stack, and calculation results are pushed back onto it. Although this concept may seem obscure at first, RPN has the advantage of being extremely easy, and therefore fast, for a computer to analyze. (op. cit.: Wikipedia)
