module top;

    class base;
      
      rand bit[7:0] a[];
      constraint a_cn
      {
        a.size == 10;
        foreach(a[i])
        {
          a[i] == (i+1) ** 2;
         
        }
      }
          
       function void post_randomize();
         a.shuffle(); 
       endfunction
    endclass
            
    initial begin
      base b;
      b = new();
      b.randomize();
      foreach(b.a[i])
        $display("%0d",b.a[i]);
