Log Analyzer

Strings Parsing Data Analysis

You are given an array of log entries, where each log entry is a string in the following format:

YYYY-MM-DD HH:MM:SS - LEVEL - MESSAGE
  • YYYY-MM-DD HH:MM:SS represents the timestamp of the log entry.
  • LEVEL is one of: INFO, WARN, or ERROR.
  • MESSAGE is an arbitrary text describing the log event.

Write a function that processes this array of log entries and performs the following tasks:

  1. Count Logs per Level: Determine the number of log entries for each log level.

  2. Timestamp Range: Identify the earliest and the latest timestamps present in the logs.

  3. Sorted Messages by Level: For each log level, compile a list of log messages sorted in ascending order based on their timestamps.

The output should be a structured representation that includes the counts per log level, the earliest and latest timestamps, and the sorted messages grouped by their log levels.

Consider handling edge cases, such as an empty input array or log entries with an invalid format, according to the requirements of your chosen programming language.

You are free to choose any programming language for your implementation.
