Example:

1. (5 points) Write an assembly program to test if the MSB in the register al is set If it is set, then divide the content of al by 4 using the appropriate shift instruction and exit. - Else, if it is not set, then multiply the content of al by 8 using the appropriate shift instruction and exit. When checking al MSB, do not change al content Assume that al is equal to the signed integer 18h. You need to come up with the appropriate mask to check the MSB. Run your program using the debugger to verify your answers
