How do you plan to solve it?

module x_detector (
    input  [1:0] a,
    output       eq_logic,
    output   reg eq_case
);
    // TODO: implement both comparisons
    assign eq_logic = a == 2'bx1;
    always @(*) begin
        case(a)
        2'bx1 : eq_case = 1'b1;
        default : eq_case = 1'b0;
        endcase
    end
