在字符串数组中打印出特定字符出现次数最多的字符串

Question

我需要从一个字符串数组中打印出字符串，该数组中特定字符的出现次数最多。

示例：

{"I","have","feelings"} , 'e' 打印 "feelings".

{"doodlidoo","foo","moon"} , 'o' 打印"doodlidoo".

到目前为止我已经想出了这个，它找到了每个字符串的长度。我只需要弄清楚如何打印单个字符串。

 public static String MostLettersInWord(String[] list, char c)
 {
    for (int x = 0; x < list.Length; x++)
     {
      int count = list[x].Split(c).Length - 1;
     }
     return list[0];
 }

Answer 1

有很多方法可以做到这一点，但是按照您的方式并保持简单和基本，只需在此处添加比较功能

string answer;
int prevCount = 0, count = 0;
for (int x = 0; x < list.Length; x++)
{
     int count = list[x].Split(c).Length - 1;
     if(count>prevCount)
     {
         answer = list[x];
         prevCount = count;
     }


}
return answer;

Answer 2

您可以使用 LINQ 轻松完成：

string result = list.OrderByDescending(str => str.Max(m => m == c)).First();

Answer 3

试试这个：-

var word = words.OrderByDescending(x => x.Count(z => z == c)).First();

Working Fiddle.

Answer 4

如果您要查找具有相同最大特定字符数的所有单词，以下查询将 select 它们：

List<string> words = new List<string> { "I", "have", "feelings", "meet" };

char ch = 'e';
var results =
    words
    .Where(w => w.Contains(ch))
    .Select(w => new
    {
        Word = w,
        CharCount = w.Count(c => c.Equals(ch))
    })
    .OrderByDescending(x => x.CharCount)
    .GroupBy(x => x.CharCount)
    .First()
    .Select(x => x.Word)
    .ToList();
