只有這種跟easy沒兩樣的medium才寫得出來了

3163. String Compression III

public string CompressedString(string word)
{
    if (word.Length == 1)
    {
        return $"1{word}";
    }
    var result = new StringBuilder();
    var lastCharacter = word[0];
    var lastCount = 1;

    for (int i=1;i<word.Length;i++)
    {
        if (word[i] == word[i-1] & lastCount < 9)
        {
            lastCount++;
        }
        else
        {
            result.Append($"{lastCount}{word[i - 1]}");
            lastCount = 1;
            lastCharacter = word[i];
        }
    }

    result.Append($"{lastCount}{word[word.Length-1]}");
    return result.ToString();
}
