Solve Problem 4 only

Problem - 1 Write an assembly language routine to perform the following operations, using two's complement signed binary numbers: Add the two decimal numbers 126 and - 90. Subtract the decimal number 30 from the sum. Increment the result by one. Store the contents of the A-register in the memory location 20FF. Set the A-register. Indicate the contents of the A-register (in Hex.) after each instruction execution. Problem - 2 Realize the first three operations of problem - 1 using only four Instructions. Problem - 3 Write an assembly language routine to perform the following operations, indicating the contents of the A and B registers (in Hex.) after each instruction execution: Add the two decimal numbers 57 and -112. Subtract the decimal number -69 from the sum. Decrement the result by one. Store the contents of the B- register in the memory location 28FF (Do not change the contents of the A-register) Subtract the B - register from the A- register. Problem - 4 Follow the contents of S, Z, P, and CY flags after each instruction execution for problems 1 &3.
