Question
The purpose of this assignment is to write a program in LC-3 machine language to find if a given input is
a power of 2 and a perfect square. If it is then, write its exponent (as power of 2) as the result otherwise,
write -1 as the result.
Description:
Find if a given number N at location x2FFE is, a power of 2 and a perfect square; If yes, write its exponent (k where N=2^k) to x2FFF, else write a -1 to x2FFF
Notes:
Program must be at x3000.
Program must be written in binary
Do not assume any values in registers
