1. Correctness: The logic for finding the first occurrence is correct, but the logic for finding the last occurrence could be improved. The condition if mid ==n-1 or nums[mid]<nums[mid+1] is correct, but the implementation could be more concise.
2. Edge Cases: Ensure that the solution handles edge cases like an empty array or an array with a single element correctly. The current implementation does not explicitly check for these cases, but it seems to handle them implicitly.
3. Code Quality: Remove the print statements (print("second") and print(mid)) as they are not necessary for the solution and could affect performance in large inputs.
4. Efficiency: Consider combining the logic for finding the first and last occurrences into a single function to reduce redundancy. This would make the code more maintainable and easier to understand.
5. Best Practices: Follow best practices by using helper functions for binary search, as shown in the reference solution. This makes the code more modular and easier to debug.

Overall, the solution is on the right track but needs some refinements to handle all edge cases and improve code quality.
