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 wire [3:0] A, B; 
output wire [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);
