Question

Hello, I am studying data structures and algorithms and I am not sure how to solve this problem? Can anyone please show me how to solve step by step?

thanks in advance

Assume the usual precedence and associativity of the arithmetic operators. a. [5 points] Convert the following infix expression to postfix. Examining the expression from left to right, show the complete contents of the operator stack after the processing of each operator, each parenthesis, and the end of the expression. The stack grows from bottom to top.) E F G A B C D Answer: after after after after after after after after after after after end

Explanation / Answer

Infix expression : A / ( B + C ) - ( D - E + F ) / G

Put all operands in Posfix expression and operators on the stack. When an operator of higher precedence is there on the top of stack and a lower precedence operator is scanned from infix expression pop the higher priority operator before pushing the lower priority operator. Add the opening parenthesis on the stack but when a closing parenthesis is scanned pop all operators from the stack upto the opening parenthesis.

Posfix expression : A B C + / D E F + - G / -

+ + - - ( ( ( ( ( / / / / / - - - - - - -
