Infix and postfix are the notations to write the expressions. The infix notation put operators in between the operands. The postfix notation put operators after their operands. Write a program convert from infix notation to postfix notation.
Infix (5 + 3) * 12 / 3
Postfix: 5 3 + 12 * 3 /
Infix : 1+3*4/5 Postfix : 134*5/+
