Polish notation (PN), also known as normal Polish notation (NPN), Łukasiewicz notation, Warsaw notation, Polish prefix notation or simply prefix notation, is a mathematical notation in which operators precede their operands, in contrast to the more common infix notation, in which operators are placed between operands.
What is Reverse Polish Notation give example?
For example, the following RPN expression will produce the sum of 2 and 3, namely 5: 2 3 +. Reverse Polish notation, also known as postfix notation, contrasts with the “infix notation” of standard arithmetic expressions in which the operator symbol appears between the operands.
