74. Gated SR Latch

How do you plan to solve it?

module sr_latch_enable (
    input  EN,
    input  S,
    input  R,
    output Q,
    output Qn
);
	// Write your code here
    reg Q_r;
    reg Qn_r;

    always @(*) begin
        if (EN) begin
            if (S && R) begin
                Q_r  = 1'b0; // illegal -> reset
                Qn_r = 1'b1;
            end else if (S && !R) begin
                Q_r  = 1'b1; // set
                Qn_r = 1'b0;
            end else if (!S && R) begin
                Q_r  = 1'b0; // reset
                Qn_r = 1'b1;
            end
        end
    end

    assign Q  = Q_r;
    assign Qn = Qn_r;
