Question 8

Please explain your answers

Recall that an application of the Stack ADT is postfix expression evaluation. As a reminder, here is pseudocode for the algorithm: scan the given postfix expression from left to right; for each symbol in postfix if operand then push its value onto a stack S; if operator then { pop operand2; pop operand1; apply operator to compute operand1 op operand2; push result back onto stack S; } return value at top of stack; Use the algorithm described above to evaluate the following postfix expression: 5 6 2 + * 2 11 * 5 % + What is the returned value?
