Question

所以我一直在努力用C#写一个函数接收单词的字符串数组（在被函数从字符串接收到单词数组之前被拆分）。

所以我一直在尝试做的是一个函数，它检查是否在整个数组中除了words[0]（words是单词数组的名称）之外是否有显示更多的字母超过 3 次（至少 3 次）。

比如这句话：

Why llll ddd ssssssss !!!!!!!?

因为没有一个字母在一个单词中出现超过 3 次 - 这样的单词不存在。该函数的基础如下所示：

public bool MultipleCheck(string[] words)
{

}

到目前为止我想出了什么...我知道它有错误...我还没有修复它：

public bool AttachmentsCheck(string[] words)
{

    string currentWord;
    int wordCounter = 0;

    for (int i=0; i < words.Length; i++)
    {
        currentWord = words[i];
        for (int j = 0; j < currentWord.Length; j++)
        {
            char[] wordArr = currentWord.ToCharArray();
            for (int k=0; k < wordArr.Length; k++)
            {
                if (wordArr[k]==wordArr[wordArr.Length-k])
                {
                    wordCounter++;
                }
            }
        }
        if (wordCounter => 3)
        {
            return false;
        }
    }
    return true;
}

我希望这能奏效

private static Tuple<bool, string> ValidateWord(string[] words)
{
    bool foundResult = false;
    List<string> all3CharWords = new List<string>();
    string wordWith3SameChar = string.Empty;

    foreach (var word in words)
    {
        var resultTuple = ValidateWord(word);
        if (resultTuple.Item1)
        {
            foundResult = true;
            all3CharWords.Add(resultTuple.Item2);
        }
    }

    if (foundResult)
    {
        wordWith3SameChar = String.Join(";", all3CharWords.ToArray());
    }

    return new Tuple<bool, string>(foundResult, wordWith3SameChar);
}


private static Tuple<bool, string> ValidateWord(string words)
{
    bool foundResult = false;
    string wordWith3SameChar = string.Empty;
    List<string> traversedChars = new List<string>();
    for(int i = 0; i < words.Length; i++)
    {
        if (!traversedChars.Contains(words[i].ToString()))
        {
            string tripleChar = $"{words[i]}{words[i]}{words[i]}";
            if (words.Contains(tripleChar))
            {
                foundResult = true;
                wordWith3SameChar = words;
                break;
            }
        }
    }

    return new Tuple<bool, string>(foundResult, wordWith3SameChar);
}

按如下方式调用即可得到答案

var resultTuple = ValidateWord("Why llll ddd ssssssss".Split(' ').ToArray());
if (resultTuple.Item1)
{
    Console.WriteLine($"The following words have 3 similar charecters: " + resultTuple.Item2);
}
else
{
    Console.WriteLine("No words has consecutive 3 similar charecters.");
}

使用扩展方法来确定一个单词是否具有运行个连续的 n 个字符：

public static class StringExt {
    public static bool WordHasConsecutive(this string word, int n) {
        if (word.Length <= 1)
            return false;
        if (n < 2)
            return true;
        if (word.Length >= n) {
            var ch = word[0];
            var count = 1;
            for (int i = 1; i < word.Length; ++i) {
                if (word[i] == ch) {
                    if (++count == n)
                        return true;
                }
                else {
                    ch = word[i];
                    count = 1;
                }
            }
        }
        return false;
    }
}

答案很简单，只需 return 具有至少运行长度 3 的单词：

var ans = words.Where(w => w.WordHasConsecutive(3));
