Given the PRN expression, 63/12 + x [Note that the expression use x for multiplication instead of * so please reflect this in your answer] evaluate the PRN expression by showing your working in the given table using the algorithm below. get next token in Initialize an empty stack of operands RPN expression YES NO end of infix expression Switch (token) operand Only one value is on the stack Push onto the stack 1. Pop the top two values from the stack (if the stack does not contain two items, an error due to malformed RPN expression has occurred) 2. Apply the operator to these two values. 3. Push the resulting value back onto the stack terminate The initial values are given to you. Answer format: Your typed-in answers MUST NOT have any white space e.g. 10x2 is typed in without any white space. e.g. number 2 and number 5 are typed in as 25. e.g. empty is typed in with all lowercase. PRN Expression [Answer Stack format: NO (Answer white space format: NO between white Reason numbers and space operator. If between numbers] empty, type empty with all lowercase) 6 empty token is an operator, pop two tokens from stack, do operation for expression and push result into stack no input remain, only one token in stack and terminate token is an operand, push token into stack 63/12 + x 3/12 + x Result =
