|
||||
- SSL issues are handled for Windows environments
|
||||
- Both OpenAI and Ollama integrations are included
|
||||
- Solutions include proper error handling and user feedback
|
||||
- Code is well-documented and follows best practices
|
||||

|
||||
|
||||
1. Complete remaining day solutions (Day 2, 4, 5)
|
||||
2. Test all solutions thoroughly
|
||||
3. Prepare for PR submission
|
||||
