Reverse Polish Notation

What is RPN?

Reverse Polish Notation, commonly known as RPN, is a mathematical notation method in which every operator follows all of its operands. Unlike the standard infix notation where operators are placed between numbers, RPN places the operator after the numbers, eliminating the need for parentheses and brackets to define order of operations. Developed by Polish mathematician Jan Łukasiewicz in the 1920s, RPN became widely popular through Hewlett-Packard calculators and later influenced modern programming languages, compilers, and stack-based computing systems. In India, RPN is taught in computer science and information technology courses across universities, IIT campuses, and engineering colleges, forming a core part of compiler design and data structures curricula. It is extensively used in competitive programming, technical interviews, and software development roles. Students preparing for GATE, UGC NET, and campus placements often encounter RPN-related questions on expression evaluation and stack implementation.
