What are Postfix and Prefix Notation?
Infix notation is the standard way we write mathematical expressions, with operators placed between operands (e.g., 2 + 3). Postfix notation puts operators after operands (e.g., 2 3 +), while prefix notation places operators before operands (e.g., + 2 3).
Example:
Postfix: 2 3 +
Prefix: + 2 3
