首先,初始化三个排序的数组-
int []one = {20, 35, 57, 70}; int []two = {9, 35, 57, 70, 92}; int []three = {25, 35, 55, 57, 67, 70};
要在三排序数组中查找公共元素,请使用while循环遍历数组,并检查第二个数组与第二个数组,以及第三个-
while (i < one.Length && j < two.Length && k < three.Length) { if (one[i] == two[j] && two[j] == three[k]) { Console.Write(one[i] + " "); i++;j++;k++; } else if (one[i] < two[j]) i++; else if (two[j] < three[k]) j++; else k++; }
您可以尝试运行以下代码以在三个排序的数组中查找公用元素。
using System; class Demo { static void commonElements(int []one, int []two, int []three) { int i = 0, j = 0, k = 0; while (i < one.Length && j < two.Length && k < three.Length) { if (one[i] == two[j] && two[j] == three[k]) { Console.Write(one[i] + " "); i++;j++;k++; } else if (one[i] < two[j]) i++; else if (two[j] < three[k]) j++; else k++; } } public static void Main() { int []one = {20, 35, 57, 70}; int []two = {9, 35, 57, 70, 92}; int []three = {25, 35, 55, 57, 67, 70}; Console.Write("Common elements: "); commonElements(one, two, three); } }
输出结果
Common elements: 35 57 70
