1002. Find Common Characters

找共通字串

Example 1:

Input: words = ["bella","label","roller"]
Output: ["e","l","l"]

想法: 沒有，就硬幹

C# code:
public class Solution
{
    public IList<string> CommonChars(string[] words)
    {
        var count = new int[26];
        for (int i = 0; i < count.Length; i++)
        {
            count[i] = words[0].Count(x => x == 'a' + i);
            for (int j = 1; j < words.Length; j++)
            {
                if (count[i] == 0) break;
                count[i] = Math.Min(count[i], words[j].Count(x => x == 'a' + i));
            }
        }
        var result = new List<string>();
        for (int i=0; i<count.Length; i++)
        {
            while (count[i] != 0)
            {
                result.Add(((char)('a' + i)).ToString());
                count[i]--;
            }
        }
        return result;
    }
}
