• The student has demonstrated a good understanding of binary search and its variations. The solutions are correct and efficient.
• The code is clean and well-commented, which is excellent for readability and maintainability.
• The student has correctly handled edge cases, such as empty arrays or null inputs.
• One minor suggestion: in the "Search in Rotated Sorted Array" solution, the condition if(nums[low] <= nums[mid]) could be clarified with a comment explaining that it checks if the left side is sorted.
• The student has submitted solutions for multiple problems, but the reference solution provided was only for one of them. It would be helpful to ensure that the reference solution matches the problem being evaluated.
