Implement the circuit described by the Karnaugh map below.
Try to simplify the k-map before coding it. Try both product-of-sums and sum-of-products forms. We can't check whether you have the optimal simplification of the k-map. But we can check if your reduction is equivalent, and we can check whether you can translate a k-map into a circuit.
module top_module( input a, input b, input c, input d, output out );
