Consider the following assembly program fragment:

add $$10,$ $$0,$ $$0$

addr: lw $$8,0($$$9)$

beq $$8,$ $$0,$ label

addi $$10,$ $$10,1$

addi $$9,$ $$9,4$

j addr

label: $....$

a$)$ Assume that $$9$ initially contains the byte address of the first element, Array$[0],$

of a vector array called Array which contains consecutive $32$ bit integers in

memory. Describe precisely in a sentence or two what the program fragment does.

b$)$ Suppose the initial value of $$9$ is $(2000)10($which is the byte address of A$[0]).$

Suppose the array starts with the initial values: A$[0]=1,$ A$[1]=1,$ A$[2]=-2,$

A$[3]=0,$ A$[4]=0,$ A$[5]=2.$ What values do the registers $$8,$ $$9,$ $$10$ contain when

"label" is reached?
