8. Design a digital circuit that will count the number of True responses from four students S1, S2, S3 and S4 who participated in a quiz. Think of each student as responding to a question with true(1 or false (0.The output of the circuit will be a 3-bit binary number,Y=[Y2,Y1Y0],having a value equal to the number of "TRUE" responses. The design process should include a truth table with inputs S1,S2,S3 and S4 and outputs Y2,Y1 and YO. Develop an algorithm and code to generate the truth table for it.
