58. Maximum of Two Numbers

How do you plan to solve it?

module max2_func (
    input  [7:0] a,
    input  [7:0] b,
    output [7:0] max
);
    // ---------- Predefined function (complete the body) ----------
    function [7:0] max2;
        input [7:0] x, y;
        begin
            if(x>y)
                max2=x;
            else
                max2=y;               
        end
    endfunction
    // -------------------------------------------------------------
    assign max=max2(a,b);
    // TODO: call the function to produce the output
    // assign max = max2( /* ... */ , /* ... */ );
