a. What is the value of infix expression 5 + (4 - 2 * 3 ) * 5 + 6 ?
b. Show step by step (draw it out) to change the above infix expression to postfix expression using a Stack, you need to show the contents of stack and Output
expression for each step.
c. Show step by step (draw it out) how you get the result for postfix in part 2, which should be the same value you got in part 1. Show the content of stack for each
step.
