Solving Approach

How do you plan to solve it?

Code

module jk_ff (
    input  CLK,
    input  J,
    input  K,
    output reg Q
);
always @(posedge CLK)begin
    if (J) begin
        if (K) begin
            Q <= ~Q;
        end else begin
            Q <= 1;
        end
    end else begin
        if (K) begin
            Q <= 0;
        end else begin
            Q <= Q;
        end
    end
end

endmodule
