Consider the stack-based program below: 1. PUSH \#11 2. PUSH \#12 3. PUSH #13 4. PUSH #14 5. PUSH \#15 6. ADD 7. MUL 8. SUB 9. DIV Assumptions: Arithmetic operations take two input operands, with left-most one popped first, and produce a single result operand. a) Which algebraic expression is this stack-based program evaluating? Starting off with an empty stack, what will be the final quotient on the stack, using: b) floating point registers? c) 16-bit integer registers with signed arithmetic? d) 8-bit integer registers with signed arithmetic? e) On practical implementations, what is peculiar for integer multiply and divide instructions
