1.与数组有关的题目

for (int j &＃61; 0; j ){Console.Write("{0}\t",array[j]);//当n&＃61;5的时候&＃xff0c;打印到第4个元素的时候&＃xff0c;要换行// &＃xff08;4 &＃43; 1&＃xff09;% 5 &＃61; 0if ((j &＃43; 1) % n &＃61;&＃61; 0){Console.WriteLine();}}

//请通过冒泡排序法对整数数组{ 1, 3, 5, 7, 90, 2, 4, 6, 8, 10 }实现升序排序。static int[] BoubleSort(int[] arr) {bool isSwaped &＃61; false;for (int i &＃61; 0; i 1; i&＃43;&＃43;){for (int j &＃61; 0; j 1; j&＃43;&＃43;){if (arr[j] > arr[j&＃43;1]){int temp &＃61; arr[j];arr[j] &＃61; arr[j &＃43; 1];arr[j &＃43; 1] &＃61; temp;isSwaped &＃61; true;}}if (isSwaped &＃61;&＃61; false){break;}}return arr;}

List<string> list1 &＃61; new List<string>();List<string> list2 &＃61; new List<string>();list1.AddRange(new string[] { "a", "b", "c", "d", "e" });list2.AddRange(new string[] { "d", "e", "f", "g", "h" });//调用contains方法检测某个元素是否存在另一个集合中//是&＃xff0c;则在另一个集合中删除这个元素foreach (var item in list1){if (list2.Contains(item)){list2.Remove(item);}}//int[] arr &＃61; {1,2,3,4,5,6};//if (arr.Contains(6)) //{// Console.WriteLine(true);//}
list1.AddRange(list2);foreach (var item in list1){Console.WriteLine(item);}string[] array &＃61; list1.ToArray();Console.ReadKey();
