• The solution is correct and efficient, matching the reference solution in both time and space complexity.
• The code is clean and readable, but the comment could be improved to better explain the logic behind returning low + 1. For example, you could add a comment like: "Since low ends up at the index where the missing number should be, the missing number is low + 1 (assuming 1-based indexing)."
• Consider adding a docstring to the method to explain its purpose and parameters, which is a good practice for maintainability.
• The variable name expected is clear, but you could also name it expected_value for even more clarity.
