The way to write arithmetic expression is known as a notation. An arithmetic expression can be written in three different but equivalent notations, i. These notations are named as how they use operator in expression. We shall learn the same here in this chapter. We write expression in infix notation, e. It is easy for us humans to read, write, and speak in infix notation but the same does not go well with computing devices.

Examples: 2. Since expressions in parentheses must be done first, everything on the stack is saved and the left parenthesis is pushed to provide a marker. Then when the right parenthesis is read, the stack is popped until the corresponding left parenthesis is found.
Since postfix expressions have no parentheses, the parentheses are not printed. Tower of Hanoi Problem You just clipped your first slide! Clipping is a handy way to collect important slides you want to go back to later.

Prefix to Postfix Conversion
Prefix : An expression is called the prefix expression if the operator appears in the expression before the operands. Simply of the form operator operand1 operand2. Postfix : An expression is called the postfix expression if the operator appears in the expression after the operands. Simply of the form operand1 operand2 operator. Given a Prefix expression, convert it into a Postfix expression. Conversion of Prefix expression directly to Postfix without going through the process of converting them first to Infix and then to Postfix is much better in terms of computation and better understanding the expression Computers evaluate using Postfix expression.

Data Structure - Expression Parsing
This type of notation is referred to as infix since the operator is in between the two operands that it is working on. Which operands do they work on? The expression seems ambiguous. In fact, you have been reading and writing these types of expressions for a long time and they do not cause you any problem. Each operator has a precedence level. Operators of higher precedence are used before operators of lower precedence.
