Provide tags and a correct Python 3 solution for this coding contest problem. Dr. Moriarty is about to send a message to Sherlock Holmes. He has a string s. String p is called a substring of string s if you can read it starting from some position in the string s. For example, string "aba" has six substrings: "a", "b...
