+Use the following guidelines to review the changes and suggest improvements:
+1. Find ways to simplify the code
+2. Reuse existing code as much as possible instead of writing new code
+3. Preserve as much behavior as possible in the existing code
+4. Prefer to change as few lines of code as possible
+5. Look for logical errors in the code
+6. Look for missed cases in the code
+7. Look for any other bugs
+8. Look for opportunities to improve the code's readability
