            MoveNumberArrayToEnd(array, 3);

        }

        static void MoveNumberArrayToEnd<T>(IList<T> arrayList, int num)

        {

            if (arrayList.Count < = 0 || arrayList.Count < num)

            {

                throw new RankException();

            }

            var query = (from number in arrayList

                         orderby number descending

                         select number).Take(arrayList.Count - num).Concat(arrayList.Take(num));

            query.ToList().ForEach(q => Console.WriteLine("{0}", q));
