Using only at most r$0,$ r$1,$ r$2,$ and r$3,$ return the middle value of r$0,$ r$1,$ and r$2.$

test bench:

my work:

$.$arch armv$4$

$.$syntax unified

$.$arm

$.$text

$.$align $2$

$.$global test

$.$type test, $\%$function

test:

cmp r$0,$r$1$

movgt r$3,$r$0$

movle r$3,$r$1$

cmp r$3,$r$2$

movle r$3,$r$2$

cmp r$3,$r$2$

moveq r$3,$r$0$

cmp r$3,$r$1$

movle r$0,$r$3$

movgt r$3,$r$1$

mov r$0,$r$3$

mov pc$,$ lr

not getting the correct value

solve the question based on this test bench and my work$($change what need to change$)$

make sure the middle value $2$ is the answer
