刚刚练习了冒泡算法,趁热打铁,练习鸡尾酒算法。Cocktail!
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace 鸡尾酒排序算法 { class Program { static void Main(string[] args) { int[] arr1 = new int[] { 2, 5, 3, 18, 23, 12, 13, 16, 11 }; Cocktail(arr1); for (int i = 0; i < arr1.Length; i++) { Console.Write(arr1[i] + " "); } Console.Read(); } static void change(ref int left, ref int right)//change方法来作值交换 { int temp; temp = left; left = right; right = temp; } static void Cocktail(int[] arr)//鸡尾酒排序 { int up = arr.Length - 1;//设置排序上限 int low = 0;//设置排序下限 while (low < up) { for (int i = low; i < up; i++) { if (arr[i] <= arr[i + 1]) { continue; } else { change(ref arr[i], ref arr[i + 1]); } } up--; for (int j = up; j > low; j--) { if (arr[j] >= arr[j - 1]) { continue; } else { change(ref arr[j], ref arr[j - 1]); } low++; } } } } }
