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, 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;
