要查找字符串中每个单词的频率,您可以尝试运行以下代码-
using System;
class Demo {
static int maxCHARS = 256;
static void calculate(String s, int[] cal) {
for (int i = 0; i < s.Length; i++)
cal[s[i]]++;
}
public static void Main() {
String s = "Football!";
int []cal = new int[maxCHARS];
calculate(s, cal);
for (int i = 0; i < maxCHARS; i++)
if(cal[i] > 1) {
Console.WriteLine("Character "+(char)i);
Console.WriteLine("Occurrence = " + cal[i] + " times");
}
}
}输出结果
Character l Occurrence = 2 times Character o Occurrence = 2 times
上面,我们设置了一个字符串和一个整数数组。这有助于我们获得重复的值。该方法计算-
static void calculate(String s, int[] cal) {
for (int i = 0; i < s.Length; i++)
cal[s[i]]++;
}然后打印该值,该值也显示重复的元素-
for (int i = 0; i < maxCHARS; i++)
if(cal[i] > 1) {
Console.WriteLine("Character "+(char)i);
Console.WriteLine("Occurrence = " + cal[i] + " times");
}
