i.e. If you roll number is BC123456789 you will calculate the Fibonacci of 9. The calculated Fibonacci
number is stored in the AX register.
Fibonacci(0) = 0
Fibonacci(1) = 1
Fibonacci(n) = Fibonacci(n-1)+ Fibonacci(n+2)
Explain each instruction of program with comments and also provide/paste snapshot of your assembled and
debugged program result which will be run in AFD (A Full Screen Debugger) window showing the executed
code and final result i.e. value in AX.
Note: You will only use subroutine to solve the above problem. Marks will not be awarded for using any
Note 1: keep name of assembly file according to your VU id , i.e. if your VU id is BC123456789 , you will
keep name of the assembly code file as 23456789.asm i.e. you will use last 8 digits of your id for the code
Note 2: If the arrays, files names in the screen shots will not be according to your VU id you will get zero
Note 3: In solution file you will write the assembly code and paste two screen shots.
Note 4: You will only use NASM assembler and AFD debugger only.
Answer:; Note: If you have used any other recursive approach, and answer is correct, full marks will be given to you.
; Solution 1
num: dw 9 ;vu id is bc123456789
start: mov ax, 0
mov cx, [num]
mov ax, 0x4c00
cmp cx, 1 ;check for the base condition
sub cx, 1
sub cx, 2
add ax, cx
