$(1)$ Write an assembly code that calculates the factorial.

$(2)$ At the beginning of the program, store a number in register $1($R$1).$

$(3)$ When the process is complete, store the answer in register $0($R$0).$

plz only use support arm emulator instruction sets

The complete assembly program$/$code$.$ Your code must work for at least $3!,4!,$

$5!,$ and $6!.$ You are required to use loop$($s$),$ conditional branch$($s$),$ and function$($s$)$
