answer all please

1. Design a combinational logic circuit with three inputs x,y,z and three outputs A, 8, C. When the binary input is 0,1,2 or 3, the binary output is one greater than the input. When the binary input is 4,5,6 or 7 the binary output is one less than the input. 2. There are four adjacent parking slots in a parking area. Each slot is equipped with a special sensor whose outpot is high when a car is occupying the slot and aero when it is vacant. Design and implement a logic circuit that count number of vacant spaces in the park. 3. Write the truth table that describe the following logic circuit Pirt 2: MARIFAssemblylanguase List the hexadecimal and binary machine code for the following program. Also write the contents of the symbol table for the program? 4. Write a MARiE assemble program to evaluate the expresion AuBAC-D assume the values of B=5,C=6,D=7 Hint: use the following MARe simulator link to write your assembly code hatos /Imatie is ory/
