Review Summary

Excellent work on this task! Your solution correctly identifies and sorts all the variables, meeting all the core requirements. I am approving your submission. The automated checks did find one minor style issue in app/main.py: W391 blank line at end of file. This just means there's an extra blank line at the end of the file that you can remove. This doesn't affect your solution's correctness, which is great. Keep up the fantastic work!
