Calculate the exact delay$/$clock cycles $($cc$)$ for the below delay subroutine: $($every default instruction

is $1$ cc$,$ correct branch is $1$ cc$,$ incorrect branch is $2$ cc$,$ and RET is $4$ cc$.$ PS: QDELAY, D$0,$ D$1$ and

D$2$ are labels.

QDELAY:

ldi r$18,41$

ldi r$19,150$

ldi r$20,128$

L$1$: dec r$20$

brne L$1$

dec r$19$

brne L$1$

dec r$18$
