◇Overview
The document discusses expression evaluation using Stack data structures. It covers the conversion of expressions from infix notation to postfix notation and the subsequent evaluation of postfix expressions using stacks. Shunting Yard algorithm by E.W. Dijkstra is mentioned as a method for this conversion.
◇Important Formulas & Operator Precedence
| Operator | Associativity | Precedence Level |
|---|---|---|
^ (Exponentiation) | Right-to-Left | 3 (Highest) |
*, / (Multiplication, Division) | Left-to-Right | 2 |
+, - (Addition, Subtraction) | Left-to-Right | 1 (Lowest) |
◇Theoretical Framework: Shunting Yard & Postfix Evaluation Pipelines
1. Dijkstra's Shunting Yard Algorithm (Infix to Postfix)
2. Postfix Expression Stack Evaluation Pipeline
