81. JK Flip-Flop

How do you plan to solve it?

module jk_ff (
    input  CLK,
    input  J,
    input  K,
    output reg Q
);
 always @(posedge CLK) begin
     case({J , K})
      2'b00: Q <= Q;
      2'b01: Q <= 1'b0;
      2'b10: Q <= 1'b1;
      2'b11: Q <= ~Q;
      default: Q <= Q;
     endcase
 end
endmodule
