Problem C
Code Theft

The screening would work as follows: Every time new code was checked in, the full contents of the changed files where matched against a repository of known open source code. For each file the longest match, in number of consecutive lines, should be reported.

Comparison is done line by line. Empty lines, and lines only containing space, are ignored during comparison and not counted. Leading and trailing spaces should be ignored completely and consecutive space characters inside the lines are treated as one single space. The comparison is case-sensitive.

Input

Test data starts with the number $0 \le N \le 100$ of code fragments in the repository. Then follows, for each code fragment, one line containing the file name that the fragment was fetched from and the contents of the fragment on subsequent lines. File names will neither contain whitespace nor be guaranteed to be unique. The name is at most 254 characters long. Each fragment is terminated by ***END*** on a line by its own. This line is not considered being part of the fragment.

After the fragments in the repository have all been listed, comes the actual code snippet to find matches for. This snippet is also terminated by ***END*** on a line by its own.

Lines are guaranteed to be no longer than $254$ characters. No code fragment will be longer than $10000$ lines. Any code and file name lines will only contain the ASCII characters 32-126. The total size of the input file will not exceed $10^6$ characters.

Output

Output the number of matching consecutive lines (empty lines not counted) in a longest match from the repository, followed by a space-separated list of the file names of each fragments containing a match of this length, given in the order that the matching fragments were presented in the repository description. If no fragments match, write the number 0 on a line of its own.
