解法一：

java

class Solution {
    public List<String> commonChars(String[] A) {
        int[][] temp = new int[26][A.length];
        for (int i = 0; i < A.length; i++) {
            for (byte aByte : A[i].getBytes()) {
                temp[aByte - 97][i]++;
            }
        }
        List<String> list = new LinkedList<>();
        for (int i = 0; i < temp.length; i++) {
            int count = 100;
            for (int i1 = 0; i1 < A.length; i1++) {
                if(temp[i][i1]<count) count = temp[i][i1];
            }
            for (int j = 0; j < count; j++) {
                list.add(Character.toString((char)(i+97)));
            }
        }
        return list;
    }
}
