And quick question, does this type of question belong to Electrical Engineering or Computer Science?

Q2. (9 pts) Design a combinational circuit system. Design a combinational circuit with three inputs x,y,z, and three outputs A,B,C. Note that both xyz and ABC represent a three-bit binary number where x and A are the most significant bits, whereas z and C are the least significant bits. When a binary input xyz is 0(000),1(001),2(010), or 3(011), the binary output ABC is two more than the input xyz. When the binary input is 4(100),5(101),6(110), or 7 (111), the binary output ABC is two less than the input xyz. To design the required circuit, please answer all the following sub-questions one by one. Q2-1. (lpt) Draw a truth table of inputs xyz and outputs ABC
