| Input String | Output Stack | Operator Stack |

To convert an infix expression to postfix notation, you can use the following steps:
- Create an empty stack
- Start scanning the infix expression from left to right
- If the current character is an operand, append it to the result string
- If the current character is an operator, push it onto the stack
- If the current character is a left parentheses, push it onto the stack
- If the current character is a right parentheses, pop operators from the stack and append them to the result string until you reach a left parentheses. Discard the left and right parentheses.
- Repeat steps 2-6 until you have scanned the entire expression
- Pop any remaining operators from the stack and append them to the result string
