1. Correctness: All three solutions are correct and handle edge cases appropriately.
2. Time Complexity: All solutions achieve O(log n) time complexity, which is optimal for these problems.
3. Space Complexity: All solutions use O(1) space, which is optimal.
4. Code Quality: The code is well-structured and readable. The comments are helpful, but the student could consider adding more detailed comments for complex logic, especially in the binary search conditions.
5. Efficiency: The solutions are efficient. For the "find-minimum-in-rotated-sorted-array" problem, the student could simplify the logic by removing the check for the pivot condition (mid is smaller than neighbors) since the problem guarantees a unique minimum. The current approach is correct but slightly more complex than necessary.

Strengths:

• Clear and concise logic.
• Good handling of edge cases.
• Appropriate use of binary search for all problems.

Areas for Improvement:

• Simplify the logic for "find-minimum-in-rotated-sorted-array" by leveraging the problem's guarantee of a unique minimum.
• Consider adding more detailed comments for complex conditions to aid readability.
