Complete the second part using LC-3 instructions.
Exercises 1. Left shifting a number by 1 bit is equivalent to performing what operation on this number? 2. Given a number in R1, extract the highest 4 bits of R1 into R2. For example: R1 0110110001110101 R2 0000000000000110 Hint 1: In 2's complement, the highest bit of a negative number is 1 . The highest bit of a positive number or zero is 0 . Hint 2: Use left shift to turn the second highest bit to be the highest bit
