+'''
+Given an array A of strings made only from lowercase letters, return a list of all characters that show up in all strings within the list (including duplicates).  For example, if a character occurs 3 times in all strings but not 4 times, you need to include that character three times in the final answer.
+
+You may return the answer in any order.
+
+ 
+
+Example 1:
+
+Input: ["bella","label","roller"]
+Output: ["e","l","l"]
+Example 2:
+
+Input: ["cool","lock","cook"]
+Output: ["c","o"]
