42. Equality Operators

How do you plan to solve it?

module x_detector (
    input  [1:0] a,
    output       eq_logic,
    output       eq_case
);
    //TODO: implement both comparisons
    assign eq_logic = (a == 2'bx1);   //logical equality
    assign eq_case  = (a === 2'bx1);  //case equality

endmodule
