Question $1$: The initial contents of data register eax, ebx, and ecx are $($in hexadecimal$)$:

EAX $=4521$FFDD

EBX$=$EAFC$7890$

ECX$=00002$A$18$

Compute the contents of EFLAGS bits N$,$ Z$,$ V and C after the execution of each instruction. Use the original contents of the registers for each question

a$)$ ADD ax$,$ bx

b$)$ ADD ebx, ecx

c$)$ SUB ebx, ecx

d$)$ ADD bx$,$ FF$00$h

e$)$ SUB ebx, $0012345$Fh
