Question

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?
