Programming Challenge: Log File Analyzer (Jan 3, 2025)

Write a program that reads a server log file and analyzes it to provide the following information:

1. The total number of requests.
2. The top 5 IP addresses making requests.
3. The most requested resource (URL).
4. The number of 4xx and 5xx error codes encountered.

Bonus:

• Add a feature to identify failed login attempts by looking for specific patterns like "login failed" or "authentication error."
• Allow the user to input the path to the log file.

Example Output:

Total Requests: 12,345
Top 5 IPs:
  1. 192.168.1.1 - 1,234 requests
  2. 10.0.0.5 - 987 requests
  ...
Most Requested Resource: /index.html
4xx Errors: 456
5xx Errors: 123
