The input consists of multiple test cases. Each test case contains exactly one line, which
The last test case is followed by a line containing a '#'.
For each test case, print a line containing the test case number( beginning with 1) followed by the substring of maximum repetition number. If there are multiple substrings of maximum repetition number, print the lexicographically smallest one.
