12. Vector Bitwise Operators

How do you plan to solve it?

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