Question

.NET中 数组array1与数组array2，取出两个数组的交集的最大偶数和最小偶数

Answer 1

int[] array1 = new int[] { 23, 16, 4, 19, 22, 34, 3, 26 }; int[] array2 = new int[] { 19, 22, 3, 26, 23, 16, 4 };
List<int> interList = new List<int>();
foreach (int number in array1)
{
if ((number % 2 == 0) && (0 <= Array.IndexOf(array2, number)))
{
interList.Add(number);
}
}

if (interList.Count >= 2)
{
interList.Sort();
Console.WriteLine("交集最大偶数为:{0}, 最小偶数为:{1}", interList[interList.Count - 1], interList[0]);
}
else if (interList.Count == 1)
{
Console.WriteLine("交集最大偶数与最小偶数均为:{0}", interList[0]);
}
else
{
Console.WriteLine("两个数组无偶数交集");
}
