Strengths:

• The student provided two different solutions, showing a good understanding of multiple approaches.
• The code is well-commented and structured, making it easy to understand.
• The use of binary search is a good attempt to achieve logarithmic time complexity.

Areas for Improvement:

• The binary search implementation has a logical flaw. The termination condition and return statement need to be adjusted to correctly identify the missing number. The current implementation might return incorrect results when the missing number is at the beginning or end of the array.
• The formula approach, while correct, is less efficient for large arrays compared to the binary search approach. It would be better to focus on optimizing the binary search solution.
• The binary search function includes print statements for debugging, which should be removed in the final version.

Suggested Fixes:

• For the binary search approach, adjust the loop condition to while l <= r and ensure the return statement correctly identifies the missing number by checking the difference between the element and its index.
• Remove debugging print statements from the final code.
• Consider using the binary search approach as the primary solution due to its better time complexity.
