Question
Write in Java.
(Convert infix to postfix)
Note:
Postfix notation is a way of writing expression without using parentheses. For example, the expression ( 11 + 12 ) * 13 would be written as 11 12 + 13 *
Assume that ALWAYS there is a space between operands and operators in the input expression.
Use two stacks, one to store the operands and one to store the operators.
Your program only accpets following operators :
( )
+
-
/
*
Write a method to converts an infix expression into a postfix expression using the following method:
String infixToPostfix(String expression)
For example, the method should convert the infix expression
( 13 + 25 ) * 34 to 13 25 + 34 *
and
20 * ( 10 + 30 ) to 20 10 30 + *.
--(Do NOT change ANY of the given code below, just add to it)---
--Do not remove any of the given code below. Just add more code to it.
- solution.java:
import java.util.*;

class InfixToPostfix {
public String infixToPostfix(String expression) {
