                      unique{a[i]}; }
constraint c2{foreach(b[i])  b[i] inside{[1:100]};
                      b[i]!=a[i];}
function void post_randomize();
$display("a=%d, b=%d", a, b);
endfunction

module tb;

initial begin
num.randomize();

constraint c {
a.size == 10;
b.size == 10;
unique {a,b};
}

Unique key word makes sure that both a and b have unique elements wrt each other
as well. If we want to have some elements common in both a and b, we can put
unique in different unique statements. Repetition is not guaranteed, but
possible.
