Question
Data Structure required to evaluate infix to postfix is _________
- a. Stack
- b. Heap
- c. Queue
- d. Pointer
Solution
The correct data structure required to evaluate infix to postfix expressions is a Stack.
Explanation
- Infix notation is the common arithmetic and logical formula notation, where operators are written in-between their operands (e.g., A + B).
- Postfix notation (or Reverse Polish Notation) is a mathematical notation in which every operator follows all of its operands (e.g., AB+).
To convert from infix to postfix notation, a stack is used to temporarily hold operators and parentheses while ensuring that they are applied in the correct order according to their precedence and associativity rules.
Final Answer
a. Stack
