Given with 3 inputs, A, B, and C, and the 3 outputs of X, Y, and Z. Find the simplified expression when the binary input is 4, 5,6, or 7, the binary output is two less than the input. When the binary input is 0, 1, 2, or 3, the binary output is three greater than the input.

Provide the truth table, and simplify the expression using the K-map table method.
