Question: Implement a circuit with 3 inputs x, y, z and 3 outputs A, B ,C. When the input is 0, 1, 2 or 3, the output is one greater than the input. When the input is 4, 5, 6, or 7, the output is one less than the input.
My problem here is that when I enter 011 in my circuit the output should have been 100 instead it is giving me 110. What have I done wrong?

There are no groupings of 1's (Karnaugh maps) when B-output is generated, so all AND gates (4 of them) should be with 3-inputs (4073 type gates):
B=(Xi*Yi*Z) + (Xi*Y*Zi) + (X*Yi*Zi) + (X*Y*Z)
where index i is used for inverted input.
