Log Analyzer

You are given a series of log entries. Each log entry contains a timestamp and a message separated by a comma and a space. Your task is to analyze the logs and output three statistics:

• Total number of logs.
• The earliest and the latest timestamp (formatted as $\texttt{\text{earliest} \; \text{latest}}$ with a single space between them).
• The most frequent log message.

If there are no logs, output 0 for the count and empty strings for the timestamps and the message.

Note: In case of a tie for the most frequent message, output the one that appears first in the input order.

inputFormat

The first line contains an integer n representing the number of log entries. Each of the next n lines contains a log entry in the following format:

timestamp, message

Here, timestamp is in the format YYYY-MM-DD HH:MM:SS and message is a string that can contain spaces.

outputFormat

Output three lines:

1. The total number of logs.
2. A single line with the earliest and latest timestamps separated by a single space.
3. The most frequent log message.

If there are no logs, print 0 on the first line and print empty lines for the second and third lines.
