Question

The postfix form of A*B+C/D is?

(a) *AB/CD+

(b) AB*CD/+

(c) A*BC+/D

My question is taken from Stack Operations topic in portion Abstract Data Types of Data Structures & Algorithms I

The question was posed to me by my college professor while I was bunking the class.

Answer 1

Right choice is (b) AB*CD/+

To explain: Infix expression is (A*B)+(C/D)

AB*+(C/D)

AB*CD/+. Thus postfix expression is AB*CD/+.
