Problem $2$: $(4$ marks$)$ Write program in assembly language

a$)$ If the register values and memory location values as follows, update their values after finishing executing the following MIPS $(2$ marks$)$

add $$s4,$ $$s2,$ $$s1$

$Iw$ $$s3,12($$$s1)$

addi $$s2,$ $$s3,-12$

$sw$ $$s2,-4($$$s4)$

$\backslash$table$[[$Register$,$Value,$\backslash$table$[[$Last$],[$value$]],$Memory Location,Value,$\backslash$table$[[$Last$],[$value$]]],[$S$1,12,,12,16,],[$S$2,16,,16,20,],[$S$3,20,,20,24,],[$S$4,24,,24,26,]]$

b$)$ Assuming $$s1=00004000$ find the content of the destination registers in the following statements: $(2$ marks$)$

Iw $s$2,0($$$s1),$$$s2=$

addi $$s3,$$$s2,34,$$$s3=$

lh $s $4,4($$$s1),$#$$s4=$
