36. 4-Input NAND Gate Primitive

How do you plan to solve it?

module nand4_prim (
    input  a,
    input  b,
    input  c,
    input  d,
    output y
);
    // TODO: instantiate the built-in NAND gate primitive
    // nand <instance_name> ( <out>, <in1>, <in2>, <in3>, <in4> );
    nand nand1(y, a, b, c, d);
