3. (35 points) Complete the following table by writing different representations of a number in different columns of each row. Write "overflow" or "underflow" if the representation doesn't exist. Note: Each representation can show numbers between a min value and a max value. If the number exceeds the max value, then overflow happens and if the number is less 1 than the min value, then underflow happens. For example, integers greater than 127 cause an overflow for 8-bit two's complement representation; while integers less than - 128 cause an underflow for the same representation
