Busiest Minute

You are given a series of login timestamps in the format \(hh:mm:ss\). Your task is to determine the busiest minute, i.e., the minute with the highest number of logins. In case of a tie, output the earliest minute (in lexicographical order, which corresponds to the chronological order).

The result should be printed in the format \(hh:mm\) along with the count of logins during that minute. For example, if the login timestamps are 13:45:30, 13:46:00, 13:46:30, 13:47:00 and 13:47:30, then the busiest minute is 13:46 with 2 logins.

inputFormat

The first line contains an integer (n) which denotes the number of login entries. Each of the next (n) lines contains a login timestamp in the format hh:mm:ss.

outputFormat

Output a single line containing the busiest minute in the format hh:mm followed by a space and then the number of logins during that minute.## sample
