獲取字串中出現次數最多的字元的 C# 程式
要獲取字串中出現次數最多的字元,遍歷給定字串的長度並查找出現次數。
有了這個,設定一個新陣列進行計算 −
for (int i = 0; i < s.Length; i++) a[s[i]]++; }
我們上面使用過的值 −
String s = "livelife!"; int[] a = new int[maxCHARS];
現在顯示字元和出現次數 −
for (int i = 0; i < maxCHARS; i++) if (a[i] > 1) { Console.WriteLine("Character " + (char) i); Console.WriteLine("Occurrence = " + a[i] + " times"); }
我們來看看完整的程式碼 −
示例
using System; class Program { static int maxCHARS = 256; static void display(String s, int[] a) { for (int i = 0; i < s.Length; i++) a[s[i]]++; } public static void Main() { String s = "livelife!"; int[] a = new int[maxCHARS]; display(s, a); for (int i = 0; i < maxCHARS; i++) if (a[i] > 1) { Console.WriteLine("Character " + (char) i); Console.WriteLine("Occurrence = " + a[i] + " times"); } } }
輸出
Character e Occurrence = 2 times Character i Occurrence = 2 times Character l Occurrence = 2 times
