Write a Java program.

Have the user input an infix expression, for example: (5+7)+3+(6*4*3)+((7+4)*3)

Your program should output an equivalent postfix expression: 5 7 + 3 + 6 4 * 3 * + 7 4 + 3 * +

(no guarantee that the above is the only correct solution)

You should use the parser you wrote in the first homework and add in open and close parenthesis.

The only mathematical operations you need to worry about are +, -, *, and /.

The input string should conform to the requirements of your parser (maybe you need a space before and after an operator, number or parenthesis.
