冒泡排序及折半查找

冒泡排序：

            两层循环            

1.外层循环：循环趟数      n-1；            

2.内层循环：两两比较的次数      n-2；   

            int[] shuzu = new int[10]{1,9,5,6,2,3,4,7,8,10 };            

            for (int i = 0; i < shuzu.length; i++)            

            {                

                   for (int j = i; j < shuzu.length - 1; j++)                

                   {                    

                        if (shuzu[i] > shuzu[j + 1])                    

                       {                        

                             int zhong = shuzu[i];                        

                             shuzu[i] = shuzu[j + 1];                        

                             shuzu[j + 1] = zhong;                    

                        }

               

                  }            

              }            

//遍历数组            

foreach (int a in shuzu)            

{                

     console.writeline(a);            

}

折半查找：

            int[] a = new int[8] { 5,9,10,12,26,35,62,85};            

            int find = Convert.ToInt32(Console.ReadLine());

            int kaiShi=0, jieShu=a.Length-1, zhongJian;

            zhongJian = (kaiShi + jieShu) / 2;
