$(2)(5$ marks$)$ Computer Aracheiture question, Suppose that you are given some $1-$bit shifter$($s$),2-$bit shifter$($s$),$ and $4-$bit

shifter$($s$)$ with two control signals $s_1$ and $s_0,$ as discussed in our lectures. If the shift

amount in an ALU is represented by a $4-$bit number $a_3{a}_2{a}_1{a}_0.$ Only use the above shifters

to create a shifting component for the ALU and DRAW THE FULL SOLUTION!
