```verilog

module tb();
  int q[$]={32'd11,32'd2,32'd13,32'd4,32'd15,32'd6,32'd17,32'd8,32'd19,32'd10};
  int a[$];
  int k;

initial begin
  k = 5;
  q.shuffle();
  for(int i=0;i<k;i++) a[i] = q[i];
  foreach(a[ii]) $display("before a[%0d] is : ",ii,a[ii]);
  a.sort();
  foreach(a[ii]) $display("after a[%0d] is : ",ii,a[ii]);
end
endmodule
