WebRules for prefix to postfix expression using stack data structure: Scan the prefix expression from right to left, i.e., reverse. If the incoming symbol is an operand then push it into the stack. If the incoming symbol is an operator then pop two operands from the stack. WebThese changes to the position of the operator with respect to the operands create two new expression formats, prefix and postfix . Prefix expression notation requires that all operators precede the two operands that they work on. Postfix, on the other hand, requires that its operators come after the corresponding operands.
