Evaluate Arithmetic Expressions
Explore techniques to evaluate arithmetic expressions containing addition, subtraction, multiplication, and division without parentheses. Understand how to convert infix expressions to postfix notation using stacks and evaluate them step-by-step. Learn two main approaches including the use of operator precedence and two-pass evaluation to efficiently compute expression results.
Statement
Given an arithmetic expression as a string, evaluate its result. For simplicity, let’s assume that there are no parentheses in the expression and only the following binary operations are allowed: (+ - * /).
Examples
Here are a few examples of expressions and their results:
