![4(c): Design an "unconventional" priority encoder as follows: It has 3 inputs D0, D1 and D2 and
outputs A1, A0 and Valid. The input combination [D1,D0] = [11] is guaranteed to never happen,
that is, both D1 and DO cannot be 1 at the same time. If D2 is 1, then the output code [A1A0]=[10].
Else it is either [01] or [00] depending on which of D1 or DO is logic 1. If any input is 1, Valid=1,
else Valid=0.
