声明一个2D数组-
int[] a = new int[] { 65, 45, 32, 97, 23, 75, 59 };
假设您想要第K个最小整数,即第5个最小整数。首先对数组进行排序-
Array.Sort(a);
获取第五个最小元素-
a[k - 1];
让我们看完整的代码-
using System; using System.IO; using System.CodeDom.Compiler; namespace Program { class Demo { static void Main(string[] args) { int[] a = new int[] { 65, 45, 32, 97, 23, 75, 59 }; //第k个最小元素 int k = 5; Array.Sort(a); Console.WriteLine("Sorted Array..."); for (int i = 0; i < a.Length; i++) { Console.WriteLine(a[i]); } Console.Write("The " + k + "th smallest element = "); Console.WriteLine(a[k - 1]); } } }
