$11$: add $s$0,$$t$0,$$t$1$

$12$: sub $t$2,$$s$0,$$t$3$

$13$: add $t$0,$$so$,$$t$2$

$14$: lw $s$1,200($$$0)$

$15$: add $t$1,$$t$2,$$s$1$

$16$: sub $s$2,$$t$3,$$s$3$

you can perform the following Re$-$Ordering steps $*$

move $15$ after $13$

move $15$ before $12$

move $13$ before $14$

move $16$ before or after all other instructions

the following WAR dependencies are correct $*$

$11,13($TO$)$

$13,15($T$2)$

$14,15($S$1)$

$11,12($SO$)$

$12,15($T$2)$

$11,13($SO$)$

$12,16($S$2)$

$12,15($T$2)$

$12,13($T$2)$
