• The student's solution is well-implemented and correctly solves the problem. The binary search approach is efficiently used to find the missing number.
• The code is clean and easy to understand, with good variable naming and structure.
• One minor suggestion would be to add a comment explaining the logic of comparing arr[mid] with mid + 1 to make it even clearer for someone reading the code.
• The solution could also benefit from a simple test case in the main method to demonstrate its usage, similar to the reference solution, although this might not be required depending on the problem constraints.
