• Strengths:

  • The student has a clear understanding of binary search and its variations.
  • The code is well-commented, making it easy to follow the logic.
  • The solutions handle edge cases effectively, such as when the target is not found or when the array is already sorted.
  • The use of helper functions in problem1 (binarySearchFirst and binarySearchSecond) is a good practice.

• Areas for Improvement:

  • In problem1, the student could consider combining the two binary search functions into a single function with a parameter to indicate whether to find the first or last occurrence. This would reduce code duplication.
  • In problem3, the condition nums[mid + 1] > nums[mid] could potentially lead to an out-of-bounds error if mid is the last element. The student has handled this by checking mid == nums.size() - 1 in the peak condition, but it's worth noting for clarity.
  • The main functions in each problem could be more robust by including more test cases to cover all edge scenarios.
