Prefix to Postfix conversion

 Steps to convert prefix expression to postfix

1. Scan the given prefix expression from right to left character by character.

2. If the character is an operand, push it into the stack.

3. But if the character is an operator, pop the top two values from stack.

   Concatenate this operator with these two values (1^st top value+2^nd top value+operator) to get a new string.

4. Now push this resulting string back into the stack.
