MIPS Exercise -- Arithmetic Evaluation (stack-based) Write an MIPS program to evaluate 3ab - 2bc - 5a + 20ac - 16 Prompt the user for the values for a, b, and c, all single-precision floating-point values. To evaluate this, use as few registers as possible. Use the stack to hold all of the intermediate values. Write the final value to the monitor with an appropriate descriptive message
