If you have any doubts, please give me comment...

using System;

class Excercise {

    public static void Main () {

        string[] items = { "ROME", "LONDON", "NAIROBI", "CALIFORNIA", "ZURICH", "NEW DELHI", "AMSTERDAM", "HOUSTON", "PARIS" };

        string[] sortedItems = (string[]) items.Clone ();

        for (int i = 0; i < sortedItems.Length; i++) {

            for (int j = 0; j < sortedItems.Length-i-1; j++) {

                int len1 = sortedItems[j].Length;

                int len2 = sortedItems[j+1].Length;

                if (len1 > len2 || (len1==len2 && sortedItems[j].CompareTo(sortedItems[j+1])>0)) {

                    string temp = sortedItems[j];

                    sortedItems[j] = sortedItems[j+1];

                    sortedItems[j+1] = temp;

                }

            }

        }

        Console.WriteLine ("Here is the arranged list:");

        for (int i = 0; i < sortedItems.Length; i++) {

            Console.WriteLine (sortedItems[i]);

        }

        Console.WriteLine ("Here is the original list:");

        for (int i = 0; i < items.Length; i++) {

            Console.WriteLine (items[i]);

        }

    }
