12. Vector Bitwise Operators

How do you plan to solve it?

module bitwise_ops_demo(A,B,AND_OUT,OR_OUT,XOR_OUT,XNOR_OUT);
  input[3:0]A;
  input[3:0]B;
  output[3:0]AND_OUT,OR_OUT,XOR_OUT,XNOR_OUT;
  assign AND_OUT = A & B;
  assign OR_OUT = A | B;
  assign XOR_OUT = A ^ B;
  assign XNOR_OUT = ~(A ^ B);
