Design a combinational circuit whose inputs are two 4-bit unsigned binary integers, X, and Y, and a control signal MAX/MIN. The output of the circuit is a 4-bit unsigned integer Z such that Z=0 if X=Y; otherwise, Z=MAX(X,Y) if MAX/MIN=1, and Z=MIN(X,Y) if MAX/MIN=0. Assume the multiplexer has enable input. If the enable is not active, the output of the multiplexer is zero.
