Write an assembly program on the $8086$ instructions set. And using the string instructions to carry on the following task$($s$)$:

The program should declare an array string and variable as:

String$1$ db $$I like Assembly and Microprocessors but Marwan$$

Ans db $?$

The program should then copy the string to ES: DI $(04000$:$0$D$10),$ then find how many times the letter $$a$$ or $$A$$ appears in the string and store the result in Ans.

The program should use two subroutines, the first to copy the string from string$1$ to ES:DI$.$ The second is to count the number of times the string contains the upper or lower case of the letter $$A$.$Write an assembly program on the $8086$ instructions set.
